REMAINDER(3)			   BSD Library Functions Manual 		     REMAINDER(3)

NAME
     remainder -- floating-point remainder function

SYNOPSIS
     #include <math.h>

     double
     remainder(double x, double y);

     float
     remainderf(float x, float y);

DESCRIPTION
     The remainder() and remainderf() functions compute the value r such that r = x - n*y, where
     n is the integer nearest the exact value of x/y.

     If there are two integers closest to x/y, n shall be the even one. If r is zero, it is given
     the same sign as x.

SPECIAL VALUES
     remainder(x, y) returns a NaN and raises the "invalid" floating-point exception if x is
     infinite or y is 0.

SEE ALSO
     math(3)

STANDARDS
     The remainder() and remainderf() functions conform to ISO/IEC 9899:1999(E).
