POW(3)

NAME
1.45 `pow', `powf'--x to the power y

SYNOPSIS
     #include <math.h>
     double pow(double X, double Y);
     float powf(float X, float Y);

DESCRIPTION
`pow' and `powf' calculate X raised to the exponent 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'.

PORTABILITY
`pow' is ANSI C. `powf' is an extension.
