# gmp_intval

(PHP 4 >= 4.0.4, PHP 5)

gmp_intval -- Convert GMP number to integer

## Description

int gmp_intval ( resource gmpnumber )

This function allows to convert GMP number to integer.

警告
This function returns a useful result only if the number actually fits the PHP integer (i.e., signed long type). If you want just to print the GMP number, use gmp_strval().

範例 1. gmp_intval() example

`<?php // displays correct result echo gmp_intval("2147483647") . "\n"; // displays wrong result, above PHP integer limit echo gmp_intval("2147483648") . "\n"; // displays correct result echo gmp_strval("2147483648") . "\n"; ?>`

The printout of the above program will be:

    2147483647
    2147483647
    2147483648
