POW(3)                     Linux Programmer's Manual                    POW(3)



NAME
       pow, powf, powl - power functions

SYNOPSIS
       #include <&lt;math.h>&gt;

       double pow(double x, double y);
       float powf(float x, float y);
       long double powl(long double x, long double y);

       Link with -lm.

DESCRIPTION
       The pow() function returns the value of x raised to the power of y.

ERRORS
       EDOM   The argument x is negative and y is not an integral value.  This
              would result in a complex number.

CONFORMING TO
       SVr4, 4.3BSD, C89.  The float and long double variants are C99 require-
       ments.
