0.19.0 - 2026-07-30

0.18.0 - 2026-06-14

💥 Breaking changes

The following breaking change only affects you if you're using named arguments:

• BigInteger::fromBytes() now uses $bytes as the parameter name

🐛 Bug fixes

• of() no longer accepts a trailing newline (\n) in the input string; such input now throws NumberFormatException
• of() now consistently throws NumberFormatException for exponents too large to process, instead of IntegerOverflowException in some cases
• BigInteger::fromBase() now reports the invalid character with its original case in the NumberFormatException message, instead of lower-casing it

⚡️ Performance improvements

• BigInteger::gcd() no longer exhausts memory on large inputs when the GMP extension is not installed
• BigInteger::modInverse() no longer exhausts memory on large inputs, and is faster when the GMP extension is not installed

👌 Static analysis improvements

• Narrowed parameter and return types with static analysis annotations:
  • nthRoot()'s $n is now positive-int
  • BigInteger::toBase(), toArbitraryBase(), toBytes() and BigRational::toRepeatingDecimalString() now return non-empty-string

0.17.2 - 2026-05-25

✨ New features

• New methods: BigInteger::nthRoot() and BigDecimal::nthRoot() compute the nth root of a number (#113 by @​Pablo1Gustavo)

0.17.1 - 2026-04-19

👌 Improvements

• More precise float approximations in BigRational::toFloat()

0.17.0 - 2026-03-17

💥 Breaking changes

• Deprecated method BigDecimal::hasNonZeroFractionalPart() has been removed, use ! $number->getFractionalPart()->isZero() instead
• Exception constructors and factory methods are now @internal
