I've never encountered any IEEE FP code that ever, and I mean ever, checked the 
'exception' sticky flag that IEEE operations require.

Outside of a FP test suite, that is.

Nobody has ever turned on the FP hardware exception faults, either.

Bringing up IEEE 754 FP exceptions as an example of it being "done right" when 
it is a complete failure severely damages your case.
