Yup.  Interestingly, this is one of the very first things I can remember
being taught in "computer science" - NEVER test "reals" against absolute
values - choose a precision and test against values +/- that precision.

Mind you, that was in "autocoder", on a Ferranti Sirius, and the year was
1964.

Ah well,  yawn....
