Yup. Clean numeric code is very robust. Floating-point, fixed-point, fixed-slash, whatever.

Quite. You and virtually every Tier 1 vendor. The only system that I know of that is full gung-ho IEEE 754 (and C99) is Sun ONE Studio 9 or later on Solaris 10 or later. I have heard rumours of others but, like the Elephant's Graveyard, the closer you get to them the less definite the rumours are.
