[ocilzptj] Arithmetic in any quadratic field

If providing arithmetic with complex numbers (in an application, library, or calculator), it is only slightly more complicated to provide arithmetic in any quadratic field.  For a + b*sqrt(D), I think a, b, and D can be any real number, though mathematicians have identified rational a and b and integer D to be especially "interesting".  D=-1 is complex arithmetic.
