Remarks:
Example:
Calculates x raised to the power y.
<math.h>
double pow(double x, double y);
x
y
Returns x raised to the power y (x^y).
If y is 0, pow returns 1. If x is 0.0 and y is less than 0 pow returns inf
and a domain error occurs. If the result overflows or underflows, a
range error occurs.
