I think the higher level you can do an optimization/simplification, the
higher you should do it. Otherwise the lower layers get really messy, as
they already are in some cases. Well, in general, we should up our
floating point game. For example if Nikolay's recent load-modify-store
optimization would work on floats, that would already a nice step forward
in this case. ;) (Sorry for my ignorance, if it already works, missed that
then.)

Cool, but shouldn't this be an inline node instead for real speed++...? ;)
I mean if Trunc() and Round() are...
