int mpz_root (mpz_t rop, const mpz_t op, unsigned long int n) ¶Set rop to the truncated integer part of the nth root of op. Return non-zero if the computation was exact, i.e., if op is rop to the nth power.
void mpz_rootrem (mpz_t root, mpz_t rem, const mpz_t u, unsigned long int n) ¶Set root to the truncated integer part of the nth root of u. Set rem to the remainder, u−root**n.
void mpz_sqrt (mpz_t rop, const mpz_t op) ¶Set rop to the truncated integer part of the square root of op.
void mpz_sqrtrem (mpz_t rop1, mpz_t rop2, const mpz_t op) ¶Set rop1 to the truncated integer part
of the square root of op, like mpz_sqrt. Set rop2 to the
remainder op−rop1*rop1, which will be zero if op is a
perfect square.
If rop1 and rop2 are the same variable, the results are undefined.
int mpz_perfect_power_p (const mpz_t op) ¶Return non-zero if op is a perfect power, i.e., if there exist integers a and b, with b>1, such that op equals a raised to the power b.
Under this definition both 0 and 1 are considered to be perfect powers. Negative values of op are accepted, but of course can only be odd perfect powers.
int mpz_perfect_square_p (const mpz_t op) ¶Return non-zero if op is a perfect square, i.e., if the square root of op is an integer. Under this definition both 0 and 1 are considered to be perfect squares.
