NAME
drem - floating-point remainder function
SYNOPSIS
#include <math.h>
double drem(double x, double y);
DESCRIPTION

y. The return value is x - n * y, where n is the quotient
of x / y, rounded to the nearest integer. If the quotient
is 1/2, it is rounded to the even number.
RETURN VALUE
The drem() function returns the remainder, unless y is zero,
when the function fails and errno is set.
ERRORS
EDOM The denominator y is zero.
