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

NAME

     pow, powf - power functions

LIBRARY

     libm

SYNOPSIS

     #include <math.h>

     double
     pow(double x, double y);

     float
     powf(float x, float y);

DESCRIPTION

     The pow() family of functions return 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 whenev-
     er x is negative.

RETURN VALUES

     Upon successful completion, the described functions return x^y.

SEE ALSO

     exp(3), log(3)

STANDARDS

     The described functions conform to ISO/IEC 9899:1999 ("ISO C99").

HISTORY

     The history of the power functions dates back to Version 6 AT&T UNIX.
