Synopsis
#include <flint/radix.h>int radix_integer_sqrt(radix_integer_t s, const radix_integer_t x, const radix_t radix)sourcevoid radix_integer_sqrtrem(radix_integer_t s, radix_integer_t r, const radix_integer_t x, const radix_t radix)sourceint radix_integer_is_square(const radix_integer_t x, const radix_t radix)sourceradix_integer_sqrt sets s to \lfloor \sqrt x \rfloor and returns 1 if x is a perfect square and 0 otherwise; for negative x it returns 0 without modifying s. radix_integer_sqrtrem sets s and the remainder r = x - s^2, and throws an exception for negative x. radix_integer_is_square returns whether x is a perfect square (0 for negative x).
