This library makes use of the GMP extension to do its calculations. Install ------- [](#install) Via Composer ``` $ composer require phpmath/biginteger ``` Usage ----- [](#usage) There are two ways to create a BigInteger. A mutable or immutable BigInteger. ``` $number = new PHP\Math\BigInteger\MutableBigInteger('8273467836243255543265432745'); $number = new PHP\Math\BigInteger\ImmutableBigInteger('8273467836243255543265432745'); ``` ``` $a = new PHP\Math\BigInteger\ImmutableBigInteger('12345678901234567890'); $b = new PHP\Math\BigInteger\ImmutableBigInteger('98765432109876543210'); $sum = $a->add($b); echo $sum->value(); ``` Features -------- [](#features) This library provides a wide range of operations for working with big integers using the GMP extension: ### Basic Arithmetic [](#basic-arithmetic) - Add, subtract, multiply, and divide large numbers. - Calculate powers and roots of numbers. - Perform modulo operations. - Negate numbers and get absolute values. ### Comparison [](#comparison) - Compare numbers using `cmp()` and check equality with `equals()`. - Determine the sign of a number (positive, negative, or zero). ### Bitwise Operations [](#bitwise-operations) - Perform bitwise AND, OR, XOR, and NOT operations. - Compute Hamming distance between numbers. ### Number Theory [](#number-theory) - Calculate factorials. - Check if numbers are prime or likely prime. - Compute modular inverses. - Compute Jacobi, Legendre, and Kronecker symbols. - Calculate greatest common divisors (GCD) and least common multiples (LCM). - Check for perfect squares and perfect powers. - Find the next prime number. - Compute binomial coefficients. Change log ---------- [](#change-log) We keep a changelog for every release, have a look at the [releases overview](https://github.com/phpmath/biginteger/releases). Testing ------- [](#testing) ``` $ composer test ``` To generate code coverage: ``` $ composer test-coverage ``` Contributing ------------ [](#contributing) All contributions are welcome. Feel free to create a PR or open an issue. Security -------- [](#security) If you discover any security related issues, please create an issue in the issue tracker.
