pow, powf —
#include <math.h>
double
  
  pow(double
    x, double y);
float
  
  powf(float
    x, float y);
pow() family of functions returns
  x raised to the power of y.
If x is negative and y
    is not an integer, the global variable errno is set to
    EDOM, and on VAX a reserved operand fault is
    generated. A portable application should nevertheless ensure that
    y is an integer value whenever x
    is negative.
