GMP
If you need more precision in numbers than PHP provides by default with its built-in floating-point numbers, you can use the GNU MP (GMP) library. It provides support for arbitrary precision mathematics.
The GMP library is not enabled by default. To use it, you must
install GNU MP, Version 2.0 or later, and compile PHP with the
--with-gmp[
=DIR
]
directive.
