# gmp_init

(PHP 4 >= 4.0.4)

gmp_init -- Create GMP number

## Description

``resource gmp_init` (mixed number)`

Creates a GMP number from an integer or string. String representation can be decimal or hexadecimal. In the latter case, the string should start with `0x`.

Example 1. Creating GMP number
    <?php
        $a = gmp_init (123456);
        $b = gmp_init ("0xFFFFDEBACDFEDF7200");
    ?>

> Note: It is not necessary to call this function if you want to use integer or string in place of GMP number in GMP functions, like gmp_add(). Function arguments are automatically converted to GMP numbers, if such conversion is possible and needed, using the same rules as gmp_init().
