mini\Util\Math\Int\NativeInt final class

Documentation

Pure PHP arbitrary precision integer using decimal limbs (base 10^9)

Stores numbers as array of 9-digit chunks internally. Only converts to/from decimal string on I/O.

This is the fastest pure PHP implementation - used as fallback when GMP and bcmath extensions are not available.
