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

NAME
     fmod - floating-point remainder function

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

     double
     fmod(double x, double y);

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

RETURN VALUES
     The fmod() function returns 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.

SEE ALSO
     math(3)

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