gmp_binomial — Calculates binomial coefficient
gmp_binomial(GMP|int|string $n, int $k): GMP
Calculates the binomial coefficient C(n, k).
n 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).
kReturns the binomial coefficient C(n, k).
Throws ValueError if k is negative. Prior to PHP 8.0.0, E_WARNING was issued instead.
