Changelog

All notable changes to this project will be documented in this file.

0.12.1 - 2023-11-29

⚡️ Performance improvements

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

0.12.0 - 2023-11-26

💥 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

0.11.0 - 2023-01-16

💥 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.}

0.10.2 - 2022-08-11

👌 Improvements

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

0.10.1 - 2022-08-02

✨ New features

BigInteger::not() returns the bitwise NOT value

🐛 Bug fixes

BigInteger::toBytes() could return an incorrect binary representation for some numbers
The bitwise operations and(), or(), xor() on BigInteger could return an incorrect result when the GMP extension is not available

0.9.0 - 2020-08-18

👌 Improvements

BigNumber::of() now accepts .123 and 123. formats, both of which return a BigDecimal

💥 Breaking changes

Deprecated method BigInteger::powerMod() has been removed - use modPow() instead
Deprecated method BigInteger::parse() has been removed - use fromBase() instead

0.8.17 - 2020-08-19

🐛 Bug fix

BigInteger::toBytes() could return an incorrect binary representation for some numbers
The bitwise operations and(), or(), xor() on BigInteger could return an incorrect result when the GMP extension is not available

0.8.16 - 2020-08-18

🚑 Critical fix

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.

✨ New features

BigInteger::modInverse() calculates a modular multiplicative inverse
BigInteger::fromBytes() creates a BigInteger from a byte string
BigInteger::toBytes() converts a BigInteger to a byte string
BigInteger::randomBits() creates a pseudo-random BigInteger of a given bit length
BigInteger::randomRange() creates a pseudo-random BigInteger between two bounds

💩 Deprecations

BigInteger::powerMod() is now deprecated in favour of modPow()

0.8.15 - 2020-04-15

🐛 Fixes

added missing ext-json requirement, due to BigNumber implementing JsonSerializable

⚡️ Optimizations

additional optimization in BigInteger::remainder()

0.8.14 - 2020-02-18

✨ New features

BigInteger::getLowestSetBit() returns the index of the rightmost one bit

0.8.13 - 2020-02-16

✨ New features

BigInteger::isEven() tests whether the number is even
BigInteger::isOdd() tests whether the number is odd
BigInteger::testBit() tests if a bit is set
BigInteger::getBitLength() returns the number of bits in the minimal representation of the number

0.8.12 - 2020-02-03

🛠️ Maintenance release

Classes are now annotated for better static analysis with psalm.

This is a maintenance release: no bug fixes, no new features, no breaking changes.

0.8.11 - 2020-01-23

✨ New feature

BigInteger::powerMod() performs a power-with-modulo operation. Useful for crypto.

0.8.10 - 2020-01-21

✨ New feature

BigInteger::mod() returns the modulo of two numbers. The modulo differs from the remainder when the signs of the operands are different.

0.8.9 - 2020-01-08

⚡️ Performance improvements

A few additional optimizations in BigInteger and BigDecimal when one of the operands can be returned as is. Thanks to @tomtomsen in #24.

0.8.8 - 2019-04-25

🐛 Bug fixes

BigInteger::toBase() could return an empty string for zero values (BCMath & Native calculators only, GMP calculator unaffected)

✨ New features

BigInteger::toArbitraryBase() converts a number to an arbitrary base, using a custom alphabet
BigInteger::fromArbitraryBase() converts a string in an arbitrary base, using a custom alphabet, back to a number

These methods can be used as the foundation to convert strings between different bases/alphabets, using BigInteger as an intermediate representation.

💩 Deprecations

BigInteger::parse() is now deprecated in favour of fromBase()

BigInteger::fromBase() works the same way as parse(), with 2 minor differences:

the $base parameter is required, it does not default to 10
it throws a NumberFormatException instead of an InvalidArgumentException when the number is malformed

0.8.7 - 2019-04-20

Improvements

Safer conversion from float when using custom locales
Much faster NativeCalculator implementation 🚀

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.

0.8.6 - 2019-04-11

New method

BigNumber::sum() returns the sum of one or more numbers.

0.8.5 - 2019-02-12

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).

Thanks @manowark 👍

0.8.4 - 2018-12-07

New method

BigDecimal::sqrt() calculates the square root of a decimal number, to a given scale.

0.8.3 - 2018-12-06

New method

BigInteger::sqrt() calculates the square root of a number (thanks @peter279k).

New exception

NegativeNumberException is thrown when calling sqrt() on a negative number.

0.8.2 - 2018-11-08

Performance update

Further improvement of toInt() performance
NativeCalculator can now perform some multiplications more efficiently

0.8.1 - 2018-11-07

Performance optimization of toInt() methods.

0.8.0 - 2018-10-13

Breaking changes

The following deprecated methods have been removed. Use the new method name instead:

Method removed	Replacement method
`BigDecimal::getIntegral()`	`BigDecimal::getIntegralPart()`
`BigDecimal::getFraction()`	`BigDecimal::getFractionalPart()`

New features

BigInteger has been augmented with 5 new methods for bitwise operations:

New method	Description
`and()`	performs a bitwise `AND` operation on two numbers
`or()`	performs a bitwise `OR` operation on two numbers
`xor()`	performs a bitwise `XOR` operation on two numbers
`shiftedLeft()`	returns the number shifted left by a number of bits
`shiftedRight()`	returns the number shifted right by a number of bits

Thanks to @DASPRiD 👍

0.7.3 - 2018-08-20

New method: BigDecimal::hasNonZeroFractionalPart()

Renamed/deprecated methods:

BigDecimal::getIntegral() has been renamed to getIntegralPart() and is now deprecated
BigDecimal::getFraction() has been renamed to getFractionalPart() and is now deprecated

0.7.2 - 2018-07-21

Performance update

BigInteger::parse() and toBase() now use GMP's built-in base conversion features when available.

0.7.1 - 2018-03-01

This is a maintenance release, no code has been changed.

When installed with --no-dev, the autoloader does not autoload tests anymore
Tests and other files unnecessary for production are excluded from the dist package

This will help make installations more compact.

0.6.2 - 2017-10-02

The base class for all exceptions is now MathException. ArithmeticException has been deprecated, and will be removed in 0.7.0.

0.6.1 - 2017-10-02

A number of methods have been renamed:

BigNumber:sign() is deprecated; use getSign() instead
BigDecimal::unscaledValue() is deprecated; use getUnscaledValue() instead
BigDecimal::scale() is deprecated; use getScale() instead
BigDecimal::integral() is deprecated; use getIntegral() instead

Deprecated method BigDecimal::withScale() has been removed; use toScale() instead
Method BigNumber::toInteger() has been renamed to toInt()

0.5.4 - 2016-10-17

BigNumber classes now implement JsonSerializable. The JSON output is always a string.

0.5.3 - 2016-03-31

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.

0.5.2 - 2015-08-06

The $scale parameter of BigDecimal::dividedBy() is now optional again.

0.5.1 - 2015-07-05

New method: BigNumber::toScale()

This allows to convert any BigNumber to a BigDecimal with a given scale, using rounding if necessary.

0.5.0 - 2015-07-04

New features

Common BigNumber interface for all classes, with the following methods:
- sign() and derived methods (isZero(), isPositive(), ...)
- compareTo() and derived methods (isEqualTo(), isGreaterThan(), ...) that work across different BigNumber types
- toBigInteger(), toBigDecimal(), toBigRational() conversion methods
- toInteger() and toFloat() conversion methods to native types
Unified of() behaviour: every class now accepts any type of number, provided that it can be safely converted to the current type
New method: BigDecimal::exactlyDividedBy(); this method automatically computes the scale of the result, provided that the division yields a finite number of digits
New methods: BigRational::quotient() and remainder()
Fine-grained exceptions: DivisionByZeroException, RoundingNecessaryException, NumberFormatException
Factory methods zero(), one() and ten() available in all classes
Rounding mode reintroduced in BigInteger::dividedBy()

This release also comes with many performance improvements.

Breaking changes

BigInteger:
- getSign() is renamed to sign()
- toString() is renamed to toBase()
- BigInteger::dividedBy() now throws an exception by default if the remainder is not zero; use quotient() to get the previous behaviour

- getUnscaledValue() is renamed to unscaledValue()
- getScale() is renamed to scale()
- getIntegral() is renamed to integral()
- getFraction() is renamed to fraction()

- dividedBy() now takes a mandatory $scale parameter before the rounding mode
- toBigInteger() does not accept a $roundingMode parameter anymore
- toBigRational() does not simplify the fraction anymore; explicitly add ->simplified() to get the previous behaviour
BigRational:
- getSign() is renamed to sign()
- getNumerator() is renamed to numerator()
- getDenominator() is renamed to denominator()
- of() is renamed to nd(), while parse() is renamed to of()
Miscellaneous:
- ArithmeticException is moved to an Exception\ sub-namespace
- of() factory methods now throw NumberFormatException instead of InvalidArgumentException

0.4.3 - 2016-03-31

Backport of two bug fixes from the 0.5 branch:

BigInteger::parse() did not always throw InvalidArgumentException as expected
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.

0.4.2 - 2015-06-16

New method: BigDecimal::stripTrailingZeros()

0.4.1 - 2015-06-12

Introducing a BigRational class, to perform calculations on fractions of any size.

0.4.0 - 2015-06-12

Rounding modes have been removed from BigInteger, and are now a concept specific to BigDecimal.

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

0.3.5 - 2016-03-31

Backport of two bug fixes from the 0.5 branch:

BigInteger::parse() did not always throw InvalidArgumentException as expected
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.

0.3.4 - 2015-06-11

New methods:

BigInteger::remainder() returns the remainder of a division only
BigInteger::gcd() returns the greatest common divisor of two numbers

0.3.3 - 2015-06-07

Fix toString() not handling negative numbers.

The $roundingMode and $scale parameters have been swapped in BigDecimal::dividedBy().

0.2.2 - 2015-06-04

Stronger immutability guarantee for BigInteger and BigDecimal.

So far, it would have been possible to break immutability of these classes by calling the unserialize() internal function. This release fixes that.
