gmp_legendre — Legendre symbol
Compute the
»
Legendre symbol of num1 and
num2. num2 should be odd
and must be positive.
num1
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).
num2
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).
Should be odd and must be positive.
A GMP object.
Example #1 gmp_legendre() example
<?php
echo gmp_legendre("1", "3") . "\n";
echo gmp_legendre("2", "3") . "\n";
