NAME

fmod, fmodf - floating-point remainder function

LIBRARY

Math Library (libm, -lm)

SYNOPSIS



double fmod(double x, double y)

float fmodf(float x, float y)

DESCRIPTION

The fmod() function computes the floating-point remainder of x/ y.

RETURN VALUES

The fmod() and fmodf() functions return the value x - i * y, for some integer i such that, if y is non-zero, the result has the same sign as x and magnitude less than the magnitude of y. If y is zero, whether a domain error occurs or the fmod() function returns zero is implementation-defined.

STANDARDS

The fmod() function conforms to ANSI X3.159-1989 (``ANSI C89'') .
