gmp_abs — Absolute value
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).
Returns the absolute value of num, as a GMP number.
Example #1 gmp_abs() example
<?php
$abs1 = gmp_abs("274982683358");
$abs2 = gmp_abs("-274982683358");
echo gmp_strval($abs1) . "\n";
echo gmp_strval($abs2) . "\n";
?>The above example will output:
274982683358 274982683358
