Changelog

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

0.9.3 - 2021-08-15

🚀 Compatibility with PHP 8.1

0.9.2 - 2021-01-20

🐛 Bug fix

• Incorrect results could be returned when using the BCMath calculator, with a default scale set with bcscale(), on PHP >= 7.2 (#55).

0.9.1 - 2020-08-19

✨ 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::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 👍

• 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

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
