| 108 | |
| 109 | 🛠️ **Maintenance release** |
| 110 | |
| 111 | Classes are now annotated for better static analysis with [](https://psalm.dev/psalm](https://psalm.dev/](https://psalm.dev/). |
| 112 | |
| 113 | This is a maintenance release: no bug fixes, no new features, no breaking changes. |
| 114 | |
| 115 | ## [](https://github.com/brick/math/releases/tag/0.8.110.8.11](https://github.com/brick/math/releases/tag/0.8.11](https://github.com/brick/math/releases/tag/0.8.11) - 2020-01-23 |
| 116 | |
| 117 | ✨ **New feature** |

| 119 | `BigInteger::powerMod()` performs a power-with-modulo operation. Useful for crypto. |
| 120 | |
| 121 | ## [](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 |
| 122 | |
| 123 | ✨ **New feature** |
| 124 | |
| 125 | `BigInteger::mod()` returns the **modulo** of two numbers. The *modulo* differs from the *remainder* when the signs of the operands are different. |
| 126 | |
| 127 | ## [](https://github.com/brick/math/releases/tag/0.8.90.8.9](https://github.com/brick/math/releases/tag/0.8.9](https://github.com/brick/math/releases/tag/0.8.9) - 2020-01-08 |
| 128 | |
| 129 | ⚡️ **Performance improvements** |
| 130 | |
| 131 | A few additional optimizations in `BigInteger` and `BigDecimal` when one of the operands can be returned as is. Thanks to @tomtomsen in #24. |
| 132 | |
| 133 | ## [](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 |
| 134 | |
| 135 | 🐛 **Bug fixes** |
| 136 | |
| 137 | - `BigInteger::toBase()` could return an empty string for zero values (BCMath & Native calculators only, GMP calculator unaffected) |
| 138 | |
| 139 | ✨ **New features** |
| 140 | |
| 141 | - `BigInteger::toArbitraryBase()` converts a number to an arbitrary base, using a custom alphabet |
| 142 | - `BigInteger::fromArbitraryBase()` converts a string in an arbitrary base, using a custom alphabet, back to a number |
| 143 | |
| 144 | These methods can be used as the foundation to convert strings between different bases/alphabets, using BigInteger as an intermediate representation. |
| 145 | |
| 146 | 💩 **Deprecations** |
| 147 | |
| 148 | - `BigInteger::parse()` is now deprecated in favour of `fromBase()` |
| 149 | |
| 150 | `BigInteger::fromBase()` works the same way as `parse()`, with 2 minor differences: |
| 151 | |
| 152 | - the `$base` parameter is required, it does not default to `10` |
| 153 | - it throws a `NumberFormatException` instead of an `InvalidArgumentException` when the number is malformed |
| 154 | |
| 155 | ## [](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 |
| 156 | |
| 157 | **Improvements** |
| 158 | |
| 159 | - Safer conversion from `float` when using custom locales |
| 160 | - **Much faster** `NativeCalculator` implementation 🚀 |
| 161 | |
| 162 | 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. |
| 163 | |
| 164 | ## [](https://github.com/brick/math/releases/tag/0.8.60.8.6](https://github.com/brick/math/releases/tag/0.8.6](https://github.com/brick/math/releases/tag/0.8.6) - 2019-04-11 |
| 165 | |
| 166 | **New method** |
| 167 | |
| 168 | `BigNumber::sum()` returns the sum of one or more numbers. |
| 169 | |
| 170 | ## [](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 |
| 171 | |
| 172 | **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). |
| 173 | |
| 174 | Thanks @manowark 👍 |
| 175 | |
| 176 | ## [](https://github.com/brick/math/releases/tag/0.8.40.8.4](https://github.com/brick/math/releases/tag/0.8.4](https://github.com/brick/math/releases/tag/0.8.4) - 2018-12-07 |
| 177 | |
| 178 | **New method** |
| 179 | |
| 180 | `BigDecimal::sqrt()` calculates the square root of a decimal number, to a given scale. |
| 181 | |
| 182 | ## [](https://github.com/brick/math/releases/tag/0.8.30.8.3](https://github.com/brick/math/releases/tag/0.8.3](https://github.com/brick/math/releases/tag/0.8.3) - 2018-12-06 |
| 183 | |
| 184 | **New method** |
| 185 | |

| 193 | |
| 194 | **Performance update** |
| 195 | |
| 196 | - Further improvement of `toInt()` performance |
| 197 | - `NativeCalculator` can now perform some multiplications more efficiently |
| 198 | |
| 199 | ## [](https://github.com/brick/math/releases/tag/0.8.10.8.1](https://github.com/brick/math/releases/tag/0.8.1](https://github.com/brick/math/releases/tag/0.8.1) - 2018-11-07 |

| 219 | |
| 220 | | New method | Description | |
| 221 | | --- | --- | |
| 222 | | `and()` | performs a bitwise `AND` operation on two numbers | |
| 223 | | `or()` | performs a bitwise `OR` operation on two numbers | |
| 224 | | `xor()` | performs a bitwise `XOR` operation on two numbers | |

| 244 | |
| 245 | ## [](https://github.com/brick/math/releases/tag/0.7.10.7.1](https://github.com/brick/math/releases/tag/0.7.1](https://github.com/brick/math/releases/tag/0.7.1) - 2018-03-01 |
| 246 | |
| 247 | This is a maintenance release, no code has been changed. |
| 248 | |
| 249 | - When installed with `--no-dev`, the autoloader does not autoload tests anymore |
| 250 | - Tests and other files unnecessary for production are excluded from the dist package |
| 251 | |
| 252 | This will help make installations more compact. |
| 253 | |

| 301 | |
| 302 | 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. |
| 303 | |
| 304 | ## [](https://github.com/brick/math/releases/tag/0.5.20.5.2](https://github.com/brick/math/releases/tag/0.5.2](https://github.com/brick/math/releases/tag/0.5.2) - 2015-08-06 |

| 309 | |
| 310 | **New method: `BigNumber::toScale()`** |
| 311 | |
| 312 | This allows to convert any `BigNumber` to a `BigDecimal` with a given scale, using rounding if necessary. |
| 313 | |
| 314 | ## [](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 |
| 315 | |
| 316 | **New features** |
| 317 | - Common `BigNumber` interface for all classes, with the following methods: |
| 318 | - `sign()` and derived methods (`isZero()`, `isPositive()`, ...) |
| 319 | - `compareTo()` and derived methods (`isEqualTo()`, `isGreaterThan()`, ...) that work across different `BigNumber` types |
| 320 | - `toBigInteger()`, `toBigDecimal()`, `toBigRational`() conversion methods |
| 321 | - `toInteger()` and `toFloat()` conversion methods to native types |
| 322 | - Unified `of()` behaviour: every class now accepts any type of number, provided that it can be safely converted to the current type |
| 323 | - New method: `BigDecimal::exactlyDividedBy()`; this method automatically computes the scale of the result, provided that the division yields a finite number of digits |
| 324 | - New methods: `BigRational::quotient()` and `remainder()` |
| 325 | - Fine-grained exceptions: `DivisionByZeroException`, `RoundingNecessaryException`, `NumberFormatException` |
| 326 | - Factory methods `zero()`, `one()` and `ten()` available in all classes |
| 327 | - Rounding mode reintroduced in `BigInteger::dividedBy()` |
| 328 | |
| 329 | This release also comes with many performance improvements. |

| 331 | --- |
| 332 | |
| 333 | **Breaking changes** |
| 334 | - `BigInteger`: |
| 335 | - `getSign()` is renamed to `sign()` |
| 336 | - `toString()` is renamed to `toBase()` |
| 337 | - `BigInteger::dividedBy()` now throws an exception by default if the remainder is not zero; use `quotient()` to get the previous behaviour |
| 338 | - `BigDecimal`: |
| 339 | - `getSign()` is renamed to `sign()` |
| 340 | - `getUnscaledValue()` is renamed to `unscaledValue()` |
| 341 | - `getScale()` is renamed to `scale()` |
| 342 | - `getIntegral()` is renamed to `integral()` |
| 343 | - `getFraction()` is renamed to `fraction()` |
| 344 | - `divideAndRemainder()` is renamed to `quotientAndRemainder()` |
| 345 | - `dividedBy()` now takes a **mandatory** `$scale` parameter **before** the rounding mode |
| 346 | - `toBigInteger()` does not accept a `$roundingMode` parameter any more |
| 347 | - `toBigRational()` does not simplify the fraction any more; explicitly add `->simplified()` to get the previous behaviour |
| 348 | - `BigRational`: |
| 349 | - `getSign()` is renamed to `sign()` |
| 350 | - `getNumerator()` is renamed to `numerator()` |
| 351 | - `getDenominator()` is renamed to `denominator()` |
| 352 | - `of()` is renamed to `nd()`, while `parse()` is renamed to `of()` |
| 353 | - Miscellaneous: |
| 354 | - `ArithmeticException` is moved to an `Exception\` sub-namespace |
| 355 | - `of()` factory methods now throw `NumberFormatException` instead of `InvalidArgumentException` |

| 359 | Backport of two bug fixes from the 0.5 branch: |
| 360 | - `BigInteger::parse()` did not always throw `InvalidArgumentException` as expected |
| 361 | - 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. |

| 372 | |
| 373 | Rounding modes have been removed from `BigInteger`, and are now a concept specific to `BigDecimal`. |
| 374 | |
| 375 | `BigInteger::dividedBy()` now always returns the quotient of the division. |

| 395 | |
| 396 | `BigInteger` and `BigDecimal` now have a `getSign()` method that returns: |
| 397 | - `-1` if the number is negative |
| 398 | - `0` if the number is zero |
| 399 | - `1` if the number is positive |

| 410 | |
| 411 | Stronger immutability guarantee for `BigInteger` and `BigDecimal`. |
| 412 | |
| 413 | So far, it would have been possible to break immutability of these classes by calling the `unserialize()` internal function. This release fixes that. |
