(PHP 4 >= 4.0.4, PHP 5)
Returns array where first element is the integer square root of a (see also gmp_sqrt()), and the second is the remainder (i.e., the difference between a and the first element squared).
Example 1. gmp_sqrtrem() example
<?phplist($sqrt1, $sqrt1rem) = gmp_sqrtrem("9");list($sqrt2, $sqrt2rem) = gmp_sqrtrem("7");list($sqrt3, $sqrt3rem) = gmp_sqrtrem("1048576");echo gmp_strval($sqrt1) . ", " . gmp_strval($sqrt1rem) . "\n"; echo gmp_strval($sqrt2) . ", " . gmp_strval($sqrt2rem) . "\n"; echo gmp_strval($sqrt3) . ", " . gmp_strval($sqrt3rem) . "\n"; ?>
The printout of the above program will be:
3, 0 2, 3 1024, 0
