DREM(3)

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  quo-
       tient  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.
