NAME

     drem - floating-point remainder function


SYNOPSIS

     #include <math.h>

     double drem(double x, double y);


DESCRIPTION

     The drem() function computes the remainder of dividing x  by
     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.
