gmp_rootrem — Take the integer part and remainder of nth root

Beschreibung

function gmp_rootrem(GMP|int|string $num, int $nth): array

Takes the nth root of num and returns the integer component and remainder of the result.

Parameter-Liste

num

Ein GMP-Object, ein Integer oder eine Zeichenkette, die als Zahl interpretiert werden kann, wobei die gleiche Logik gilt, als ob die Zeichenkette in gmp_init() mit automatischer Erkennung der Basis verwendet würde (d. h. wenn base gleich 0 ist).

nth

The positive root to take of num.

Rückgabewerte

A two element array, where the first element is the integer component of the root, and the second element is the remainder, both represented as GMP numbers.

Fehler/Exceptions

Throws a ValueError if nth is less than 1, or if nth is even and num is negative.

Prior to PHP 8.0.0, an E_WARNING was raised instead.
