**CIGAL Reference Manual, Chapter 3 (Functions): rem**
===== Rem -- Calculate the remainder after performing integer division =====
**usage: result = rem(x,y)**\\
**or: result = rem(x)**

If REM is called with two arguments it calculates the integer remainder
left over after dividing the first value by the second.  That is, RESULT is:
                  x - integer(x/y) * y
        (where x and y are treated as integers).

If REM is called with a single argument it returns the non-integral
part of each X value.  That is, RESULT would be:
                  x - integer(x)

The number of elements in the output variable, RESULT, is the same as
the number of elements in the input variable X.
