FMOD(3)                 System Library Functions Manual                FMOD(3)

NAME
     fmod, fmodf - floating-point remainder functions

SYNOPSIS
     #include 

     double
     fmod(double x, double y);

     float
     fmodf(float x, float y);

DESCRIPTION
     The fmod() function computes the floating-point remainder of x/ y.  The
     fmodf() function is a single precision version of fmod().

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 mag-
     nitude 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 X3.159-1989 (``ANSI C'').
