0.8.7

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

New method

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

0.8.5

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

New method

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

0.8.3

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

Performance update

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

0.8.1

Performance optimization of toInt() methods.

0.8.0

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

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

Performance update

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