POW(3) BSD Programmer's Manual POW(3)
pow, powf - power functions
#include <math.h> double pow(double x, double y); float powf(float x, float y);
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.
Upon successful completion, the described functions return x^y.
The described functions conform to ISO/IEC 9899:1999 ("ISO C99").
The history of the power functions dates back to Version 6 AT&T UNIX. MirOS BSD #10-current September 13, 2011 1
