+```
+
+## 🔄 Mapeo de Migración
+
+### **Archivo → Controlador**
+
+#### **ObtenCiudades.php → CiudadesController.php**
+```php
+// ORIGINAL (ObtenCiudades.php)
+$sql = "{CALL sapObtenListadoCiudadesxNombre}";
+$stmt = sqlsrv_query($conn, $sql);
+while ($row = sqlsrv_fetch_array($stmt, SQLSRV_FETCH_ASSOC)) {
+    $data[] = $row;
+}
+
+// MIGRADO (CiudadesController.php)
+public function obtenerCiudades(): JsonResponse {
+    $ciudades = DB::select('EXEC sapObtenListadoCiudadesxNombre');
+    return response()->json([
+        "tipo" => 0,
+        "mensaje" => "OK",
+        "data" => $ciudades
+    ]);
+}
+```
+
+#### **ObtenEmpresas.php → EmpresasController.php**
+```php
+// ORIGINAL (ObtenEmpresas.php)
+$sql = "{CALL sapObtenEmpresas}";
+$stmt = sqlsrv_query($conn, $sql);
+while ($row = sqlsrv_fetch_array($stmt, SQLSRV_FETCH_ASSOC)) {
+    $data[] = $row;
+}
+
+// MIGRADO (EmpresasController.php)
+public function obtenerEmpresas(): JsonResponse {
+    $empresas = DB::select('EXEC sapObtenEmpresas');
+    return response()->json([
+        "tipo" => 0,
+        "mensaje" => "OK", 
+        "data" => $empresas
+    ]);
+}
+```
+
+### **Mejoras Implementadas**
+
+1. **Manejo de Errores Mejorado:**
+   ```php
+   // Original: die(json_encode(["error" => sqlsrv_errors()]));
+   // Nuevo: try-catch con respuestas HTTP apropiadas
+   ```
+
+2. **Alternativas con Query Builder:**
+   ```php
+   // Nuevo método alternativo sin procedimientos almacenados
+   DB::table('ciudades')->select('*')->orderBy('nombre')->get();
+   ```
+
+3. **Middleware CORS:**
+   ```php
+   // Configurado para acceso desde frontend
+   'Access-Control-Allow-Origin' => '*'
+   ```

+# 📚 Configuración Swagger UI para WSCONCILIA API
+
+## 🎯 Integración de OpenAPI/Swagger en Laravel
+
+### 1. **Instalar L5-Swagger (Opcional)**
+```bash
+composer require darkaonline/l5-swagger
+php artisan vendor:publish --provider "L5Swagger\L5SwaggerServiceProvider"
+```
+
+### 2. **Configurar Swagger UI Manual**
+
+Crear archivo `public/swagger-ui.html`:
+```html
+<!DOCTYPE html>
+<html>
+<head>
+    <title>WSCONCILIA API Documentation</title>
+    <link rel="stylesheet" type="text/css" href="https://unpkg.com/swagger-ui-dist@4.15.5/swagger-ui.css" />
+</head>
+<body>
+    <div id="swagger-ui"></div>
+    <script src="https://unpkg.com/swagger-ui-dist@4.15.5/swagger-ui-bundle.js"></script>
+    <script>
+        SwaggerUIBundle({
+            url: '/openapi.yaml',
+            dom_id: '#swagger-ui',
+            presets: [
+                SwaggerUIBundle.presets.apis,
+                SwaggerUIBundle.presets.standalone
+            ]
+        });
+    </script>
+</body>
+</html>
+```
+
+### 3. **Copiar openapi.yaml a public**
+```bash
+cp openapi.yaml public/
+```
+
+### 4. **Acceder a la documentación**
+- OpenAPI Spec: `http://localhost:8000/openapi.yaml`
+- Swagger UI: `http://localhost:8000/swagger-ui.html`
+
+## 🔧 Validación del OpenAPI
+
+### **Validar sintaxis:**
+```bash
+# Con swagger-codegen (si tienes instalado)
+swagger-codegen validate -i openapi.yaml
+
+# Online validator
+# Subir a: https://validator.swagger.io/
+```
+
+### **Generar clientes:**
+```bash
+# Generar cliente JavaScript
+swagger-codegen generate -i openapi.yaml -l javascript -o client-js
+
+# Generar cliente PHP
+swagger-codegen generate -i openapi.yaml -l php -o client-php
+```
+
+## 📋 Endpoints Documentados
+
+| Endpoint | Método | Descripción |
+|----------|--------|-------------|
+| `/health` | GET | Health check |
+| `/info` | GET | API info |
+| `/v1/ciudades` | GET | Ciudades (SP) |
+| `/v1/ciudades-alt` | GET | Ciudades (QB) |
+| `/v1/empresas` | GET | Empresas (SP) |
+| `/v1/empresas-alt` | GET | Empresas (QB) |
+| `/v1/empresas/{id}` | GET | Empresa por ID |
+
+## 🎨 Características del OpenAPI
+
+- ✅ **OpenAPI 3.0.3** estándar
+- ✅ **Ejemplos completos** para todas las respuestas
+- ✅ **Esquemas detallados** para Ciudad y Empresa
+- ✅ **Documentación de errores** con ejemplos
+- ✅ **Parámetros de consulta** documentados
+- ✅ **Información de migración** incluida
+- ✅ **Metadatos de base de datos** documentados

+
+## [0.13.1](https://github.com/brick/math/releases/tag/0.13.1) - 2025-03-29
+
+✨ **Improvements**
+
+- `__toString()` methods of `BigInteger` and `BigDecimal` are now type-hinted as returning `numeric-string` instead of `string` (#90 by @vudaltsov)

+
+⚡️ **Performance improvements**
+
+- Division in `NativeCalculator` is now faster for small divisors, thanks to [@Izumi-kun](https://github.com/Izumi-kun) in [#87](https://github.com/brick/math/pull/87).
+
+👌 **Improvements**

+
+## [0.12.1](https://github.com/brick/math/releases/tag/0.12.1) - 2023-11-29
+
+⚡️ **Performance improvements**
+
+- `BigNumber::of()` is now faster, thanks to [@SebastienDug](https://github.com/SebastienDug) in [#77](https://github.com/brick/math/pull/77).
+
+## [0.12.0](https://github.com/brick/math/releases/tag/0.12.0) - 2023-11-26
+
+💥 **Breaking changes**
+
+- Minimum PHP version is now 8.1
+- `RoundingMode` is now an `enum`; if you're type-hinting rounding modes, you need to type-hint against `RoundingMode` instead of `int` now
+- `BigNumber` classes do not implement the `Serializable` interface anymore (they use the [new custom object serialization mechanism](https://wiki.php.net/rfc/custom_object_serialization))
+- The following breaking changes only affect you if you're creating your own `BigNumber` subclasses:
+  - the return type of `BigNumber::of()` is now `static`
+  - `BigNumber` has a new abstract method `from()`
+  - all `public` and `protected` functions of `BigNumber` are now `final`
+
+## [0.11.0](https://github.com/brick/math/releases/tag/0.11.0) - 2023-01-16
+
+💥 **Breaking changes**
+
+- Minimum PHP version is now 8.0
+- Methods accepting a union of types are now strongly typed<sup>*</sup>
+- `MathException` now extends `Exception` instead of `RuntimeException`
+
+<sup>* You may now run into type errors if you were passing `Stringable` objects to `of()` or any of the methods
+internally calling `of()`, with `strict_types` enabled. You can fix this by casting `Stringable` objects to `string`
+first.</sup>
+
+## [0.10.2](https://github.com/brick/math/releases/tag/0.10.2) - 2022-08-11
+
+👌 **Improvements**
+
+- `BigRational::toFloat()` now simplifies the fraction before performing division (#73) thanks to @olsavmic

+
+## [0.9.0](https://github.com/brick/math/releases/tag/0.9.0) - 2020-08-18
+
+👌 **Improvements**
+

+
+🚑 **Critical fix**
+
+- This version reintroduces the deprecated `BigInteger::parse()` method, that has been removed by mistake in version `0.8.9` and should have lasted for the whole `0.8` release cycle.
+

+
+## [0.8.15](https://github.com/brick/math/releases/tag/0.8.15) - 2020-04-15
+
+🐛 **Fixes**
+
+- added missing `ext-json` requirement, due to `BigNumber` implementing `JsonSerializable`
+
+⚡️ **Optimizations**
+
+- additional optimization in `BigInteger::remainder()`
+
+## [0.8.14](https://github.com/brick/math/releases/tag/0.8.14) - 2020-02-18
+
+✨ **New features**

+
+## [0.8.13](https://github.com/brick/math/releases/tag/0.8.13) - 2020-02-16
+
+✨ **New features**
+
+- `BigInteger::isEven()` tests whether the number is even
+- `BigInteger::isOdd()` tests whether the number is odd
+- `BigInteger::testBit()` tests if a bit is set
+- `BigInteger::getBitLength()` returns the number of bits in the minimal representation of the number
+
+## [0.8.12](https://github.com/brick/math/releases/tag/0.8.12) - 2020-02-03
+
+🛠️ **Maintenance release**
+
+Classes are now annotated for better static analysis with [psalm](https://psalm.dev/).
+
+This is a maintenance release: no bug fixes, no new features, no breaking changes.
+
+## [0.8.11](https://github.com/brick/math/releases/tag/0.8.11) - 2020-01-23
+
+✨ **New feature**
+
+`BigInteger::powerMod()` performs a power-with-modulo operation. Useful for crypto.
+
+## [0.8.10](https://github.com/brick/math/releases/tag/0.8.10) - 2020-01-21
+
+✨ **New feature**
+
+`BigInteger::mod()` returns the **modulo** of two numbers. The *modulo* differs from the *remainder* when the signs of the operands are different.
+
+## [0.8.9](https://github.com/brick/math/releases/tag/0.8.9) - 2020-01-08
+
+⚡️ **Performance improvements**
+
+A few additional optimizations in `BigInteger` and `BigDecimal` when one of the operands can be returned as is. Thanks to @tomtomsen in #24.
+
+## [0.8.8](https://github.com/brick/math/releases/tag/0.8.8) - 2019-04-25
+
+🐛 **Bug fixes**
+
+- `BigInteger::toBase()` could return an empty string for zero values (BCMath & Native calculators only, GMP calculator unaffected)
+
+✨ **New features**
+
+- `BigInteger::toArbitraryBase()` converts a number to an arbitrary base, using a custom alphabet
+- `BigInteger::fromArbitraryBase()` converts a string in an arbitrary base, using a custom alphabet, back to a number
+
+These methods can be used as the foundation to convert strings between different bases/alphabets, using BigInteger as an intermediate representation.
+
+💩 **Deprecations**
+
+- `BigInteger::parse()` is now deprecated in favour of `fromBase()`
+
+`BigInteger::fromBase()` works the same way as `parse()`, with 2 minor differences:
+
+- the `$base` parameter is required, it does not default to `10`
+- it throws a `NumberFormatException` instead of an `InvalidArgumentException` when the number is malformed
+
+## [0.8.7](https://github.com/brick/math/releases/tag/0.8.7) - 2019-04-20
+
+**Improvements**
+
+- Safer conversion from `float` when using custom locales
+- **Much faster** `NativeCalculator` implementation 🚀
+
+You can expect **at least a 3x performance improvement** for common arithmetic operations when using the library on systems without GMP or BCMath; it gets exponentially faster on multiplications with a high number of digits. This is due to calculations now being performed on whole blocks of digits (the block size depending on the platform, 32-bit or 64-bit) instead of digit-by-digit as before.
+
+## [0.8.6](https://github.com/brick/math/releases/tag/0.8.6) - 2019-04-11
+
+**New method**
+
+`BigNumber::sum()` returns the sum of one or more numbers.
+
+## [0.8.5](https://github.com/brick/math/releases/tag/0.8.5) - 2019-02-12
+
+**Bug fix**: `of()` factory methods could fail when passing a `float` in environments using a `LC_NUMERIC` locale with a decimal separator other than `'.'` (#20).
+
+Thanks @manowark 👍
+
+## [0.8.4](https://github.com/brick/math/releases/tag/0.8.4) - 2018-12-07
+
+**New method**
+
+`BigDecimal::sqrt()` calculates the square root of a decimal number, to a given scale.
+
+## [0.8.3](https://github.com/brick/math/releases/tag/0.8.3) - 2018-12-06
+
+**New method**
+
+`BigInteger::sqrt()` calculates the square root of a number (thanks @peter279k).
+
+**New exception**
+
+`NegativeNumberException` is thrown when calling `sqrt()` on a negative number.
+
+## [0.8.2](https://github.com/brick/math/releases/tag/0.8.2) - 2018-11-08
+
+**Performance update**
+
+- Further improvement of `toInt()` performance
+- `NativeCalculator` can now perform some multiplications more efficiently
+
+## [0.8.1](https://github.com/brick/math/releases/tag/0.8.1) - 2018-11-07
+
+Performance optimization of `toInt()` methods.
+
+## [0.8.0](https://github.com/brick/math/releases/tag/0.8.0) - 2018-10-13
+
+**Breaking changes**
+
+The following deprecated methods have been removed. Use the new method name instead:
+
+| Method removed | Replacement method |
+| --- | --- |
+| `BigDecimal::getIntegral()` | `BigDecimal::getIntegralPart()` |
+| `BigDecimal::getFraction()` | `BigDecimal::getFractionalPart()` |
+
+---
+
+**New features**
+
+`BigInteger` has been augmented with 5 new methods for bitwise operations:
+
+| New method | Description |
+| --- | --- |
+| `and()` | performs a bitwise `AND` operation on two numbers |
+| `or()` | performs a bitwise `OR` operation on two numbers |
+| `xor()` | performs a bitwise `XOR` operation on two numbers |
+| `shiftedLeft()` | returns the number shifted left by a number of bits |
+| `shiftedRight()` | returns the number shifted right by a number of bits |
+
+Thanks to @DASPRiD 👍
+
+## [0.7.3](https://github.com/brick/math/releases/tag/0.7.3) - 2018-08-20

+
+**Performance update**
+
+`BigInteger::parse()` and `toBase()` now use GMP's built-in base conversion features when available.
+
+## [0.7.1](https://github.com/brick/math/releases/tag/0.7.1) - 2018-03-01
+
+This is a maintenance release, no code has been changed.
+
+- When installed with `--no-dev`, the autoloader does not autoload tests anymore
+- Tests and other files unnecessary for production are excluded from the dist package
+
+This will help make installations more compact.

+- `ArithmeticException` has been renamed to `MathException`
+
+## [0.6.2](https://github.com/brick/math/releases/tag/0.6.2) - 2017-10-02
+
+The base class for all exceptions is now `MathException`.
+`ArithmeticException` has been deprecated, and will be removed in 0.7.0.
+
+## [0.6.1](https://github.com/brick/math/releases/tag/0.6.1) - 2017-10-02
+
+A number of methods have been renamed:
+
+- `BigNumber:sign()` is deprecated; use `getSign()` instead
+- `BigDecimal::unscaledValue()` is deprecated; use `getUnscaledValue()` instead
+- `BigDecimal::scale()` is deprecated; use `getScale()` instead
+- `BigDecimal::integral()` is deprecated; use `getIntegral()` instead
+- `BigDecimal::fraction()` is deprecated; use `getFraction()` instead
+- `BigRational::numerator()` is deprecated; use `getNumerator()` instead
+- `BigRational::denominator()` is deprecated; use `getDenominator()` instead
+
+The old methods will be removed in version 0.7.0.
+
+## [0.6.0](https://github.com/brick/math/releases/tag/0.6.0) - 2017-08-25
+
+- Minimum PHP version is now [7.1](https://gophp71.org/); for PHP 5.6 and PHP 7.0 support, use version `0.5`
+- Deprecated method `BigDecimal::withScale()` has been removed; use `toScale()` instead
+- Method `BigNumber::toInteger()` has been renamed to `toInt()`
+
+## [0.5.4](https://github.com/brick/math/releases/tag/0.5.4) - 2016-10-17
+
+`BigNumber` classes now implement [JsonSerializable](http://php.net/manual/en/class.jsonserializable.php).
+The JSON output is always a string.
+
+## [0.5.3](https://github.com/brick/math/releases/tag/0.5.3) - 2016-03-31
+
+This is a bugfix release. Dividing by a negative power of 1 with the same scale as the dividend could trigger an incorrect optimization which resulted in a wrong result. See #6.
+
+## [0.5.2](https://github.com/brick/math/releases/tag/0.5.2) - 2015-08-06
+
+The `$scale` parameter of `BigDecimal::dividedBy()` is now optional again.
+
+## [0.5.1](https://github.com/brick/math/releases/tag/0.5.1) - 2015-07-05
+
+**New method: `BigNumber::toScale()`**
+
+This allows to convert any `BigNumber` to a `BigDecimal` with a given scale, using rounding if necessary.
+
+## [0.5.0](https://github.com/brick/math/releases/tag/0.5.0) - 2015-07-04
+
+**New features**
+- Common `BigNumber` interface for all classes, with the following methods:
+  - `sign()` and derived methods (`isZero()`, `isPositive()`, ...)
+  - `compareTo()` and derived methods (`isEqualTo()`, `isGreaterThan()`, ...) that work across different `BigNumber` types
+  - `toBigInteger()`, `toBigDecimal()`, `toBigRational`() conversion methods
+  - `toInteger()` and `toFloat()` conversion methods to native types
+- Unified `of()` behaviour: every class now accepts any type of number, provided that it can be safely converted to the current type
+- New method: `BigDecimal::exactlyDividedBy()`; this method automatically computes the scale of the result, provided that the division yields a finite number of digits
+- New methods: `BigRational::quotient()` and `remainder()`
+- Fine-grained exceptions: `DivisionByZeroException`, `RoundingNecessaryException`, `NumberFormatException`
+- Factory methods `zero()`, `one()` and `ten()` available in all classes
+- Rounding mode reintroduced in `BigInteger::dividedBy()`
+
+This release also comes with many performance improvements.
+
+---
+
+**Breaking changes**
+- `BigInteger`:
+  - `getSign()` is renamed to `sign()`
+  - `toString()` is renamed to `toBase()`
+  - `BigInteger::dividedBy()` now throws an exception by default if the remainder is not zero; use `quotient()` to get the previous behaviour
+- `BigDecimal`:
+  - `getSign()` is renamed to `sign()`
+  - `getUnscaledValue()` is renamed to `unscaledValue()`
+  - `getScale()` is renamed to `scale()`
+  - `getIntegral()` is renamed to `integral()`
+  - `getFraction()` is renamed to `fraction()`
+  - `divideAndRemainder()` is renamed to `quotientAndRemainder()`
+  - `dividedBy()` now takes a **mandatory** `$scale` parameter **before** the rounding mode
+  - `toBigInteger()` does not accept a `$roundingMode` parameter anymore
+  - `toBigRational()` does not simplify the fraction anymore; explicitly add `->simplified()` to get the previous behaviour
+- `BigRational`:
+  - `getSign()` is renamed to `sign()`
+  - `getNumerator()` is renamed to  `numerator()`
+  - `getDenominator()` is renamed to  `denominator()`
+  - `of()` is renamed to `nd()`, while `parse()` is renamed to `of()`
+- Miscellaneous:
+  - `ArithmeticException` is moved to an `Exception\` sub-namespace
+  - `of()` factory methods now throw `NumberFormatException` instead of `InvalidArgumentException`
+
+## [0.4.3](https://github.com/brick/math/releases/tag/0.4.3) - 2016-03-31
+
+Backport of two bug fixes from the 0.5 branch:
+- `BigInteger::parse()` did not always throw `InvalidArgumentException` as expected
+- Dividing by a negative power of 1 with the same scale as the dividend could trigger an incorrect optimization which resulted in a wrong result. See #6.
+
+## [0.4.2](https://github.com/brick/math/releases/tag/0.4.2) - 2015-06-16
+
+New method: `BigDecimal::stripTrailingZeros()`
+
+## [0.4.1](https://github.com/brick/math/releases/tag/0.4.1) - 2015-06-12
+
+Introducing a `BigRational` class, to perform calculations on fractions of any size.
+
+## [0.4.0](https://github.com/brick/math/releases/tag/0.4.0) - 2015-06-12
+
+Rounding modes have been removed from `BigInteger`, and are now a concept specific to `BigDecimal`.
+
+`BigInteger::dividedBy()` now always returns the quotient of the division.
+
+## [0.3.5](https://github.com/brick/math/releases/tag/0.3.5) - 2016-03-31
+
+Backport of two bug fixes from the 0.5 branch:
+
+- `BigInteger::parse()` did not always throw `InvalidArgumentException` as expected
+- Dividing by a negative power of 1 with the same scale as the dividend could trigger an incorrect optimization which resulted in a wrong result. See #6.
+
+## [0.3.4](https://github.com/brick/math/releases/tag/0.3.4) - 2015-06-11
+
+New methods:
+- `BigInteger::remainder()` returns the remainder of a division only
+- `BigInteger::gcd()` returns the greatest common divisor of two numbers
+
+## [0.3.3](https://github.com/brick/math/releases/tag/0.3.3) - 2015-06-07
+
+Fix `toString()` not handling negative numbers.
+
+## [0.3.2](https://github.com/brick/math/releases/tag/0.3.2) - 2015-06-07
+
+`BigInteger` and `BigDecimal` now have a `getSign()` method that returns:
+- `-1` if the number is negative
+- `0` if the number is zero
+- `1` if the number is positive
+
+## [0.3.1](https://github.com/brick/math/releases/tag/0.3.1) - 2015-06-05
+
+Minor performance improvements
+
+## [0.3.0](https://github.com/brick/math/releases/tag/0.3.0) - 2015-06-04
+
+The `$roundingMode` and `$scale` parameters have been swapped in `BigDecimal::dividedBy()`.
+
+## [0.2.2](https://github.com/brick/math/releases/tag/0.2.2) - 2015-06-04
+
+Stronger immutability guarantee for `BigInteger` and `BigDecimal`.
+
+So far, it would have been possible to break immutability of these classes by calling the `unserialize()` internal function. This release fixes that.
+
+## [0.2.1](https://github.com/brick/math/releases/tag/0.2.1) - 2015-06-02
+
+Added `BigDecimal::divideAndRemainder()`
+
+## [0.2.0](https://github.com/brick/math/releases/tag/0.2.0) - 2015-05-22
+
+- `min()` and `max()` do not accept an `array` anymore, but a variable number of parameters
+- **minimum PHP version is now 5.6**
+- continuous integration with PHP 7
+
+## [0.1.1](https://github.com/brick/math/releases/tag/0.1.1) - 2014-09-01
+
+- Added `BigInteger::power()`
+- Added HHVM support
+
+## [0.1.0](https://github.com/brick/math/releases/tag/0.1.0) - 2014-08-31
+
+First beta release.
