[issue1182] Paticular decimal mod operation wrongly output NaN.

Mark Dickinson added the comment: I don't think anything's missing from Cowlishaw's test-suite. An old, buggy test (nrmx218) was both renamed (to redx218) and fixed by Cowlishaw. I think Facundo ended up with both tests---so naturally the old, broken test failed. ___
