The remainder() function
returns the decimal floating-point remainder when y is nonzero
and following the relation 
The value n is the integral
value nearest the exact value x/y and when 
then the value of
n is even.
These functions work in IEEE decimal floating-point format. See IEEE decimal floating-point for more information.
Note: To use IEEE decimal floating-point, the hardware
must have the Decimal Floating-Point Facility installed.
Returned value
If successful, remainder() returns the remainder of the division of x by y.
If y is zero, remainder() returns NaNQ and sets errno to EDOM.
