REMAINDER(3)	       FreeBSD Library Functions Manual		  REMAINDER(3)

NAME
     remainder,	remainderf, remainderl,	remquo,	remquof, remquol -- minimal
     residue functions

LIBRARY
     Math Library (libm, -lm)

SYNOPSIS
     #include <math.h>

     double
     remainder(double x, double	y);

     float
     remainderf(float x, float y);

     long double
     remainderl(long double x, long double y);

     double
     remquo(double x, double y,	int *quo);

     float
     remquof(float x, float y, int *quo);

     long double
     remquol(long double x, long double	y, int *quo);

DESCRIPTION
     remainder(), remainderf(),	remainderl(), remquo(),	remquof(), and
     remquol() return the remainder r := x - n*y where n is the	integer	near-
     est the exact value of x/y; moreover if |n	- x/y| = 1/2 then n is even.
     Consequently the remainder	is computed exactly and	|r| <= |y|/2.  But
     attempting	to take	the remainder when y is	0 or x is +-infinity is	an
     invalid operation that produces a NaN.

     The remquo(), remquof(), and remquol() functions also store the last k
     bits of n in the location pointed to by quo, provided that	n exists.  The
     number of bits k is platform-specific, but	is guaranteed to be at least
     3.

STANDARDS
     The remainder(), remainderf(), remainderl(), remquo(), remquof(), and
     remquol() routines	conform	to ISO/IEC 9899:1999 (``ISO C99'').  The
     remainder is as defined in	IEEE Std 754-1985.

HISTORY
     The remainder() and remainderf() functions	appeared in 4.3BSD and
     FreeBSD 2.0, respectively.	 The remquo() and remquof() functions were
     added in FreeBSD 6.0, and remainderl() and	remquol() were added in
     FreeBSD 8.0.
