Brick Math is a PHP library that provides arbitrary-precision arithmetic for integers, rational numbers, and decimal numbers. It is designed to overcome the limitations of PHP’s native number handling, especially for applications dealing with large numbers, financial calculations, or scientific computations. Brick Math complies with standards like IEEE 754 and avoids rounding errors inherent to floating-point arithmetic.

With this library, you can transform your internal IDs to obfuscated integers based on Knuth's integer hash. It is similar to Hashids but will generate integers instead of random strings. It is also super fast. If you will be running your code on a 32-bit system or will be working with large prime numbers it is suggested that you install the GMP extension.

Check yafu on github for the latest code. YAFU (with assistance from other free software) uses the most powerful modern algorithms (and implementations of them) to factor input integers in a completely automated way. The automation within YAFU is state-of-the-art, combining factorization algorithms in an intelligent and adaptive methodology that minimizes the time to find the factors of arbitrary input integers. Most algorithm implementations are multi-threaded, allowing YAFU to fully...

...XInt stands for eXtended Integer. In fact, they are extended in two directions - l and r. The l extension is the fact that they do not have a size limit (except for available memory) and the r extension is that they have decimal places (also unlimited). A large part of math.h has been overloaded for XInt and the rest will follow. The functions that have not been overloaded (sin etc.) can still be accessed as there are conversion operators to and from long double.

LameUtils contails LameInts (large integer numbers signed and unsigned), LameStrings, and LameArray.
