This is to say nothing of the semantic vagaries of limited-precision
floating point. It's almost impossible to even create reliable
mathematical concepts that accomodate floats, doubles, et. al.

Ain't that the plain truth. I can't speak for accommodating floats, doubles, etc. We pretty much decided to go with float or Single across the board for precision reasons for what we're doing.
