✨ **Improvements** |
| 8 |
|
| 9 |
- `__toString()` methods of `BigInteger` and `BigDecimal` are now type-hinted as returning `numeric-string` instead of `string` (#90 by @vudaltsov) |

💥 **Breaking changes** |
| 14 |
|
| 15 |
- `BigDecimal::ofUnscaledValue()` no longer throws an exception if the scale is negative |
| 16 |

| 17 |
|
| 18 |
✨ **New features** |
| 19 |
|
| 20 |
- `BigDecimal::ofUnscaledValue()` allows a negative scale (and converts the values to create a zero scale number) |

| 46 |
💥 **Breaking changes** |
| 47 |
|
| 48 |
- Minimum PHP version is now 8.1 |
| 49 |
- `RoundingMode` is now an `enum`; if you're type-hinting rounding modes, you need to type-hint against `RoundingMode` instead of `int` now |
| 50 |
- `BigNumber` classes do not implement the `Serializable` interface anymore (they use the [](https://wiki.php.net/rfc/custom_object_serializationnew custom object serialization mechanism](https://wiki.php.net/rfc/custom_object_serialization](https://wiki.php.net/rfc/custom_object_serialization)) |
| 51 |
- The following breaking changes only affect you if you're creating your own `BigNumber` subclasses: |
| 52 |
- the return type of `BigNumber::of()` is now `static` |
| 53 |
- `BigNumber` has a new abstract method `from()` |
| 54 |
- all `public` and `protected` functions of `BigNumber` are now `final` |
| 55 |

| 58 |
💥 **Breaking changes** |
| 59 |
|
| 60 |
- Minimum PHP version is now 8.0 |
| 61 |
- Methods accepting a union of types are now strongly typed<sup>*</sup> |
| 62 |
- `MathException` now extends `Exception` instead of `RuntimeException` |
| 63 |
|
| 64 |
<sup>* You may now run into type errors if you were passing `Stringable` objects to `of()` or any of the methods |
| 65 |
internally calling `of()`, with `strict_types` enabled. You can fix this by casting `Stringable` objects to `string` |
| 66 |
first.</sup> |

| 129 |
🚑 **Critical fix** |
| 130 |
|
| 131 |
- 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. |

|
| 147 |
🐛 **Fixes** |
| 148 |
|
| 149 |

|
| 186 |

⚡️ **Performance improvements** |
| 193 |
|
| 194 |
A few additional optimizations in `BigInteger` and `BigDecimal` when one of the operands can be returned as is. Thanks to @tomtomsen in #24. |
| 195 |
|
| 196 |
## [](https://github.com/brick/math/releases/tag/0.8.80.8.8](https://github.com/brick/math/releases/tag/0.8.8](https://github.com/brick/math/releases/tag/0.8.8) - 2019-04-25 |
| 197 |
|
| 198 |
🐛 **Bug fixes** |
| 199 |
|
| 200 |
- `BigInteger::toBase()` could return an empty string for zero values (BCMath & Native calculators only, GMP calculator unaffected) |
| 201 |
|
| 202 |
✨ **New features** |
| 203 |
|
| 204 |
- `BigInteger::toArbitraryBase()` converts a number to an arbitrary base, using a custom alphabet |
| 205 |
- `BigInteger::fromArbitraryBase()` converts a string in an arbitrary base, using a custom alphabet, back to a number |
| 206 |
|
| 207 |
These methods can be used as the foundation to convert strings between different bases/alphabets, using BigInteger as an intermediate representation. |
| 208 |
|
| 209 |
💩 **Deprecations** |
| 210 |
|
| 211 |
- `BigInteger::parse()` is now deprecated in favour of `fromBase()` |
| 212 |
|
| 213 |
`BigInteger::fromBase()` works the same way as `parse()`, with 2 minor differences: |
| 214 |
|
| 215 |
- the `$base` parameter is required, it does not default to `10` |
| 216 |
- it throws a `NumberFormatException` instead of an `InvalidArgumentException` when the number is malformed |
| 217 |
|
| 218 |
## [](https://github.com/brick/math/releases/tag/0.8.70.8.7](https://github.com/brick/math/releases/tag/0.8.7](https://github.com/brick/math/releases/tag/0.8.7) - 2019-04-20 |
| 219 |
|
| 220 |
**Improvements** |
| 221 |
|
| 222 |
- Safer conversion from `float` when using custom locales |
| 223 |
- **Much faster** `NativeCalculator` implementation 🚀 |
| 224 |
|
| 225 |
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. |

| 228 |
|
| 229 |
**New method** |
| 230 |
|
| 231 |
`BigNumber::sum()` returns the sum of one or more numbers. |
| 232 |
|
| 233 |

| 234 |
|
| 235 |
**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). |

| 241 |
**New method** |
| 242 |
|
| 243 |

| 244 |
|
| 245 |

**Performance update** |
| 305 |
|
| 306 |
`BigInteger::parse()` and `toBase()` now use GMP's built-in base conversion features when available. |

|
| 310 |
This is a maintenance release, no code has been changed. |
| 311 |
|
| 312 |
- When installed with `--no-dev`, the autoloader does not autoload tests anymore |
| 313 |
- Tests and other files unnecessary for production are excluded from the dist package |
| 314 |
|
| 315 |
This will help make installations more compact. |

| 372 |
|
| 373 |
**New method: `BigNumber::toScale()`** |
| 374 |
|
| 375 |
This allows to convert any `BigNumber` to a `BigDecimal` with a given scale, using rounding if necessary. |
| 376 |
|
| 377 |
## [](https://github.com/brick/math/releases/tag/0.5.00.5.0](https://github.com/brick/math/releases/tag/0.5.0](https://github.com/brick/math/releases/tag/0.5.0) - 2015-07-04 |
| 378 |
|
| 379 |
**New features** |
| 380 |
- Common `BigNumber` interface for all classes, with the following methods: |
| 381 |
- `sign()` and derived methods (`isZero()`, `isPositive()`, ...) |
| 382 |
- `compareTo()` and derived methods (`isEqualTo()`, `isGreaterThan()`, ...) that work across different `BigNumber` types |
| 383 |
- `toBigInteger()`, `toBigDecimal()`, `toBigRational`() conversion methods |
| 384 |
- `toInteger()` and `toFloat()` conversion methods to native types |
| 385 |
- Unified `of()` behaviour: every class now accepts any type of number, provided that it can be safely converted to the current type |
| 386 |
- New method: `BigDecimal::exactlyDividedBy()`; this method automatically computes the scale of the result, provided that the division yields a finite number of digits |
| 387 |
- New methods: `BigRational::quotient()` and `remainder()` |
| 388 |
- Fine-grained exceptions: `DivisionByZeroException`, `RoundingNecessaryException`, `NumberFormatException` |
| 389 |
- Factory methods `zero()`, `one()` and `ten()` available in all classes |
| 390 |
- Rounding mode reintroduced in `BigInteger::dividedBy()` |
| 391 |
|
| 392 |
This release also comes with many performance improvements. |
| 393 |

| 400 |

| 409 |

Stronger immutability guarantee for `BigInteger` and `BigDecimal`. |
| 475 |
|
| 476 |
