AzaMath - Anizoptera CMF mathematic component. Provides functionality to work with large numbers with arbitrary precision (using BCMath) and universal mumeral systems conversions (supported bases from 2 to 62 inclusive, and custom systems; pure PHP, but can use GMP and core functions for speed optimization).
AzaPhpGen - Anizoptera CMF PHP code generation (dump) component. Allows to dump complex arrays, objects, closures and basic data types as php code. In part, this can be called a some sort of serialization. You can customize your dumped php code as you wish.
