gmp_rootrem — Take the integer part and remainder of nth root
Takes the nth root of num and returns the integer component and remainder of the result.
numA 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).
nthThe positive root to take of num.
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.
