fmod(3M)							      fmod(3M)

NAME
       fmod(), fmodf(), fmodl(), fmodw(), fmodq() - remainder functions

SYNOPSIS
   HP Integrity Server Only
DESCRIPTION
       The  function  returns the floating-point remainder (f) of the division
       of x by y, where f has the same sign as x, such that  x=iy+f  for  some
       integer i, and |f| < |y|.

       is a version of it takes arguments and returns a result.

   Integrity Server Only
       is a version of it takes arguments and returns a result.

       is an version of it takes arguments and returns an result.

       is equivalent to on HP-UX systems.

USAGE
       To  use	these functions compile either with the default option or with
       the and options.

       To use (for Integrity servers) or compile also with the option.

       To use any of these functions, make sure your program includes Link  in
       the math library by specifying on the compiler or linker command line.

RETURN VALUE
       If y x returns x.

       If x y is a nonzero number, returns x.

       If x or y is NaN, returns NaN.

       If x or y is zero, returns NaN and raises the invalid exception.

ERRORS
       If y is zero or x is infinite, sets to [EDOM].

   Integrity Server
       HP-UX  functions	 on Integrity servers do not set by default.  For set‐
       ting, compile with the option.

SEE ALSO
