pow, powf : x to the power y

Synopsis

#include <math.h>
double pow(double x, double y);
float pow(float x, float y);
```### Description

pow and powf calculate x raised to the exp1.0nt y.### Returns

On success, pow and powf return the value calculated.

When the argument values would produce overflow, pow returns HUGE_VAL and set errno to ERANGE. If the argument x passed to pow or powf is a negative noninteger, and y is also not an integer, then errno is set to EDOM. If x and y are both 0, then pow and powf return 1. You can modify error handling for these functions using matherr.
