Immutable arbitrary precision integer

This is the public API for arbitrary precision integer math. Internally uses the best available implementation (GMP, bcmath, or pure PHP).

Serialization stores only the string value, so serialized data is portable across different PHP installations regardless of available extensions.

Usage: $a = BigInt::of('123456789012345678901234567890'); $b = BigInt::of(42); $result = $a->add($b)->multiply($a); echo $result; // prints the number
