remainder(3) BSD Library Functions Manual remainder(3)
NAME
remainder -- floating-point remainder function
SYNOPSIS
#include <math.h> double remainder(double x, double y); long double remainderl(long double x, long double y); float remainderf(float x, float y);
DESCRIPTION
The remainder() 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.
NOTE
The drem() function is deprecated. Please use the C99 function remainder() instead.
