Hi Helmut,

❝ Haha, I know this game and therefore, always round before the comparison. ;-)

or never bring yourself into a situation where you need to compare floats.

I've taken the worst way out and written functions that check if x is simar to y plus/minus a wee faction like 1e-8 or something. It is ugly and clumsy, it works, and it feel everytime like I am suffering defeat.
