Me too. And there isn't even anything wrong with that code. We just need
to find a way to give the compiler a hint with the clue bat.

Isn't 0x7FFFFFFF == nan in float? Maybe we could get rid of the int type
and initialize the union through the float members with 0./0.? But maybe
this is just a stupid idea.

Gosh, this is to pull my hair out. ;)
