gmp_sqrtrem
(PHP 4 >= 4.0.4, PHP 5, PHP 7, PHP 8)
gmp_sqrtrem — Square root with remainder
Parameters
num-
The number being square rooted.
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
Returns array where first element is the integer square root of
num and the second is the remainder
(i.e., the difference between num and the
first element squared).
Errors/Exceptions
Throws a ValueError if num is negative.
Prior to PHP 8.0.0, an E_WARNING was raised instead.
Examples
Example #1 gmp_sqrtrem() example
<?php
list($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 above example will output:
gmp_sqrt
