计算不同类别的参数的幂函数值。
接口定义
C interface：
complex double powc16i4(complex double x, int y);
complex double powc16i4_18(complex double x, int y);
int powi4i4(int x, int y);
int powi4i4_18(int x, int y);
int64_t powi8i4(int64_t x, int y);
int64_t powi8i4_18(int64_t x, int y);
int64_t powi8i8(int64_t x, int64_t y);
float powr4i4(float x, int y);
double powr8i4(double x, int y);
long double powr16i4(long double x, int y);
powc16i4_18、powi4i4_18仅在高精度版本提供。
