✨ New features

• New method: BigNumber::ofNullable() (#94 by @mrkh995)

✨ Compatibility fixes

• Fixed warnings on PHP 8.5 (#101 and #102 by @julien-boudry)

✨ New features

• New methods: BigInteger::clamp() and BigDecimal::clamp() (#96 by @JesterIruka)

✨ Improvements

• All pure methods in BigNumber classes are now marked as @pure for better static analysis

💥 Breaking changes

• Minimum PHP version is now 8.2
• BigNumber classes are now readonly
• BigNumber is now marked as sealed: it must not be extended outside of this package
• Exception classes are now final

✨ Improvements

• __toString() methods of BigInteger and BigDecimal are now type-hinted as returning numeric-string instead of string (#90 by @vudaltsov)

💥 Breaking changes

• BigDecimal::ofUnscaledValue() no longer throws an exception if the scale is negative
• MathException now extends RuntimeException instead of Exception; this reverts the change introduced in version 0.11.0 (#82)

✨ New features

• BigDecimal::ofUnscaledValue() allows a negative scale (and converts the values to create a zero scale number)

✨ New features

• BigDecimal::getPrecision() returns the number of significant digits in a decimal number

⚡️ Performance improvements

• Division in NativeCalculator is now faster for small divisors, thanks to @Izumi-kun in #87

👌 Improvements

• Add missing RoundingNecessaryException to the @throws annotation of BigNumber::of()

⚡️ Performance improvements

• BigNumber::of() is now faster, thanks to @SebastienDug in #77.

💥 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)
• 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

💥 Breaking changes

• Minimum PHP version is now 8.0
• Methods accepting a union of types are now strongly typed^*
• MathException now extends Exception instead of RuntimeException

^{* 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.}

👌 Improvements

• BigRational::toFloat() now simplifies the fraction before performing division (#73) thanks to @olsavmic
