Syntax
gmp_sqrtrem (val)
Parameters
val: The GMP number for which we want to compute the square root.
Return
The gmp_sqrtrem() function returns an array with 1st element as the integer square root val, whereas the 2nd element is the remainder.
Example
The following is an example:
<?php
list($sqrt, $sqrtrem) = gmp_sqrtrem("8");
echo gmp_strval($sqrt) . ", " . gmp_strval($sqrtrem) . "\n";
?>Output
