gmp_intval — Convert GMP number to integer

Description

gmp_intval(GMP|int|string $num): int

This function converts GMP number into native PHP ints.

Parameters

num: A GMP object, an int, or a string that can be interpreted as a number following the same logic as if the string was used in gmp_init() with automatic base detection (i.e. when base is equal to 0).

Return Values

The int value of num.

Examples

Example #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 above example will output:

2147483647
2147483647
2147483648

Notes

Warning

This function returns a useful result only if the number actually fits the PHP integer (i.e., signed long type). To simply print the GMP number, use gmp_strval().
