-FUNCTION
-<<fmod>>, <<fmodf>>---floating-point remainder (modulo)
-
-INDEX
-fmod
-INDEX
-fmodf
-
-ANSI_SYNOPSIS
-#include <math.h>
-double fmod(double <[x]>, double <[y]>)
-float fmodf(float <[x]>, float <[y]>)
-
-TRAD_SYNOPSIS
-#include <math.h>
-double fmod(<[x]>, <[y]>)
-double (<[x]>, <[y]>);
-
-float fmodf(<[x]>, <[y]>)
-float (<[x]>, <[y]>);
-
-DESCRIPTION
-The <<fmod>> and <<fmodf>> functions compute the floating-point
-remainder of <[x]>/<[y]> (<[x]> modulo <[y]>).
-
-RETURNS
-The <<fmod>> function returns the value
-@ifinfo
-<[x]>-<[i]>*<[y]>,
-@end ifinfo
-@tex
-$x-i\times y$,
-@end tex
-for the largest integer <[i]> such that, if <[y]> is nonzero, the
-result has the same sign as <[x]> and magnitude less than the
-magnitude of <[y]>.
-
-<<fmod(<[x]>,0)>> returns NaN, and sets <<errno>> to <<EDOM>>.
-
-You can modify error treatment for these functions using <<matherr>>.
-
-PORTABILITY
-<<fmod>> is ANSI C. <<fmodf>> is an extension.
