🛠️ **Maintenance release** |
| 92 |
|
| 93 |
Classes are now annotated for better static analysis with [](https://psalm.dev/psalm](https://psalm.dev/](https://psalm.dev/). |
| 94 |
|
| 95 |
This is a maintenance release: no bug fixes, no new features, no breaking changes. |

✨ **New feature** |
| 100 |
|
| 101 |
`BigInteger::powerMod()` performs a power-with-modulo operation. Useful for crypto. |
| 102 |
|
| 103 |
## [](https://github.com/brick/math/releases/tag/0.8.100.8.10](https://github.com/brick/math/releases/tag/0.8.10](https://github.com/brick/math/releases/tag/0.8.10) - 2020-01-21 |
| 104 |
|
| 105 |
✨ **New feature** |
| 106 |
|
| 107 |
`BigInteger::mod()` returns the **modulo** of two numbers. The *modulo* differs from the *remainder* when the signs of the operands are different. |
| 108 |
|
| 109 |

| 110 |
|
| 111 |
⚡️ **Performance improvements** |
| 112 |
|
| 113 |
A few additional optimizations in `BigInteger` and `BigDecimal` when one of the operands can be returned as is. Thanks to @tomtomsen in #24. |
| 114 |
|
| 115 |
## [](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 |
| 116 |
|
| 117 |
🐛 **Bug fixes** |
| 118 |
|
| 119 |
- `BigInteger::toBase()` could return an empty string for zero values (BCMath & Native calculators only, GMP calculator unaffected) |
| 120 |
|
| 121 |
✨ **New features** |
| 122 |
|
| 123 |
- `BigInteger::toArbitraryBase()` converts a number to an arbitrary base, using a custom alphabet |
| 124 |
- `BigInteger::fromArbitraryBase()` converts a string in an arbitrary base, using a custom alphabet, back to a number |
| 125 |
|
| 126 |
These methods can be used as the foundation to convert strings between different bases/alphabets, using BigInteger as an intermediate representation. |
| 127 |
|
| 128 |
💩 **Deprecations** |
| 129 |
|
| 130 |
- `BigInteger::parse()` is now deprecated in favour of `fromBase()` |
| 131 |
|
| 132 |
`BigInteger::fromBase()` works the same way as `parse()`, with 2 minor differences: |
| 133 |
|
| 134 |
- the `$base` parameter is required, it does not default to `10` |
| 135 |
- it throws a `NumberFormatException` instead of an `InvalidArgumentException` when the number is malformed |
| 136 |
|
| 137 |
## [](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 |
| 138 |
|
| 139 |
**Improvements** |
| 140 |
|
| 141 |
- Safer conversion from `float` when using custom locales |
| 142 |
- **Much faster** `NativeCalculator` implementation 🚀 |
| 143 |
|
| 144 |
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. |
| 145 |

| 147 |
|
| 148 |
**New method** |
| 149 |
|
| 150 |
`BigNumber::sum()` returns the sum of one or more numbers. |
| 151 |
|
| 152 |
## [](https://github.com/brick/math/releases/tag/0.8.50.8.5](https://github.com/brick/math/releases/tag/0.8.5](https://github.com/brick/math/releases/tag/0.8.5) - 2019-02-12 |
| 153 |
|
| 154 |
**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). |
| 155 |

| 160 |
**New method** |

| 298 |
**New features** |
| 299 |
- Common `BigNumber` interface for all classes, with the following methods: |
| 300 |
- `sign()` and derived methods (`isZero()`, `isPositive()`, ...) |
| 301 |
- `compareTo()` and derived methods (`isEqualTo()`, `isGreaterThan()`, ...) that work across different `BigNumber` types |
| 302 |
- `toBigInteger()`, `toBigDecimal()`, `toBigRational`() conversion methods |
| 303 |
- `toInteger()` and `toFloat()` conversion methods to native types |
| 304 |
- Unified `of()` behaviour: every class now accepts any type of number, provided that it can be safely converted to the current type |
| 305 |
- New method: `BigDecimal::exactlyDividedBy()`; this method automatically computes the scale of the result, provided that the division yields a finite number of digits |
| 306 |
- New methods: `BigRational::quotient()` and `remainder()` |
| 307 |
- Fine-grained exceptions: `DivisionByZeroException`, `RoundingNecessaryException`, `NumberFormatException` |
| 308 |
- Factory methods `zero()`, `one()` and `ten()` available in all classes |
| 309 |
- Rounding mode reintroduced in `BigInteger::dividedBy()` |
| 310 |
|
| 311 |
This release also comes with many performance improvements. |

**Breaking changes** |
| 316 |
- `BigInteger`: |
| 317 |
- `getSign()` is renamed to `sign()` |
| 318 |
- `toString()` is renamed to `toBase()` |
| 319 |
- `BigInteger::dividedBy()` now throws an exception by default if the remainder is not zero; use `quotient()` to get the previous behaviour |
| 320 |
- `BigDecimal`: |
| 321 |
- `getSign()` is renamed to `sign()` |
| 322 |
- `getUnscaledValue()` is renamed to `unscaledValue()` |
| 323 |
- `getScale()` is renamed to `scale()` |
| 324 |
- `getIntegral()` is renamed to `integral()` |
| 325 |
- `getFraction()` is renamed to `fraction()` |
| 326 |
- `divideAndRemainder()` is renamed to `quotientAndRemainder()` |
| 327 |
- `dividedBy()` now takes a **mandatory** `$scale` parameter **before** the rounding mode |
| 328 |
- `toBigInteger()` does not accept a `$roundingMode` parameter any more |
| 329 |
- `toBigRational()` does not simplify the fraction any more; explicitly add `->simplified()` to get the previous behaviour |
| 330 |
- `BigRational`: |
| 331 |
- `getSign()` is renamed to `sign()` |
| 332 |
- `getNumerator()` is renamed to `numerator()` |
| 333 |
- `getDenominator()` is renamed to `denominator()` |
| 334 |
- `of()` is renamed to `nd()`, while `parse()` is renamed to `of()` |
| 335 |
- Miscellaneous: |
| 336 |
- `ArithmeticException` is moved to an `Exception\` sub-namespace |
| 337 |
- `of()` factory methods now throw `NumberFormatException` instead of `InvalidArgumentException` |

| 341 |
Backport of two bug fixes from the 0.5 branch: |
| 342 |
- `BigInteger::parse()` did not always throw `InvalidArgumentException` as expected |
| 343 |
- 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. |

|
| 357 |
`BigInteger::dividedBy()` now always returns the quotient of the division. |

`BigInteger` and `BigDecimal` now have a `getSign()` method that returns: |
| 379 |
- `-1` if the number is negative |
| 380 |
- `0` if the number is zero |
| 381 |
- `1` if the number is positive |

| 393 |
Stronger immutability guarantee for `BigInteger` and `BigDecimal`. |
| 394 |
|
| 395 |
So far, it would have been possible to break immutability of these classes by calling the `unserialize()` internal function. This release fixes that. |
