Serializable
interface being deprecated (thanks @TRowbotham)
0.9.2 - 2021-01-20
🐛 Bug fix

and123.
formats, both of which return aBigDecimal

and()
,or()
,xor()
onBigInteger
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 version0.8.9
and should have lasted for the whole0.8
release cycle.
✨ New features
BigInteger::modInverse()
calculates a modular multiplicative inverseBigInteger::fromBytes()
creates aBigInteger
from a byte stringBigInteger::toBytes()
converts aBigInteger
to a byte stringBigInteger::randomBits()
creates a pseudo-randomBigInteger
of a given bit lengthBigInteger::randomRange()
creates a pseudo-randomBigInteger
between two bounds
💩 Deprecations
BigInteger::powerMod()
is now deprecated in favour ofmodPow()
0.8.15 - 2020-04-15
🐛 Fixes
- added missing
ext-json
requirement, due toBigNumber
implementingJsonSerializable
⚡️ 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 evenBigInteger::isOdd()
tests whether the number is oddBigInteger::testBit()

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 alphabetBigInteger::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 offromBase()
BigInteger::fromBase()
works the same way as parse()
, with 2 minor differences:
- the
$base
parameter is required, it does not default to10
- it throws a
NumberFormatException
instead of anInvalidArgumentException
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

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

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 differentBigNumber
typestoBigInteger()
,toBigDecimal()
,toBigRational
() conversion methodstoInteger()
andtoFloat()
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()
andremainder()
- Fine-grained exceptions:
DivisionByZeroException
,RoundingNecessaryException
,NumberFormatException
- Factory methods
zero()
,one()
andten()
available in all classes - Rounding mode reintroduced in
BigInteger::dividedBy()
This release also comes with many performance improvements.
Breaking changes
BigInteger
:getSign()
is renamed tosign()
toString()
is renamed totoBase()
BigInteger::dividedBy()
now throws an exception by default if the remainder is not zero; usequotient()
to get the previous behaviour

does not simplify the fraction any more; explicitly add->simplified()
to get the previous behaviour
BigRational
:getSign()
is renamed tosign()
getNumerator()
is renamed tonumerator()
getDenominator()
is renamed todenominator()
of()
is renamed tond()
, whileparse()
is renamed toof()
- Miscellaneous:
ArithmeticException
is moved to anException\
sub-namespaceof()
factory methods now throwNumberFormatException
instead ofInvalidArgumentException
0.4.3 - 2016-03-31
Backport of two bug fixes from the 0.5 branch:
BigInteger::parse()
did not always throwInvalidArgumentException
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 throwInvalidArgumentException
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 onlyBigInteger::gcd()
returns the greatest common divisor of two numbers
0.3.3 - 2015-06-07
Fix toString()
not handling negative numbers.
0.3.2 - 2015-06-07
BigInteger
and BigDecimal
now have a getSign()
method that returns:
-1
if the number is negative0
if the number is zero1
if the number is positive
0.3.1 - 2015-06-05
Minor performance improvements
0.3.0 - 2015-06-04
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.
0.2.1 - 2015-06-02
Added BigDecimal::divideAndRemainder()
0.2.0 - 2015-05-22
min()
andmax()
do not accept anarray
any more, but a variable number of parameters- minimum PHP version is now 5.6
- continuous integration with PHP 7
0.1.1 - 2014-09-01
- Added
BigInteger::power()
- Added HHVM support
0.1.0 - 2014-08-31
