You could do foating point calculations in integers. One for the full 
numbers and one for the fractions. If you do this then you also need 
correction calculation to now how far you will be off the real float.

Support for both formats does seem like a good thing to me. It gives you 
flexibility across platforms (those with FPU and those without). I am a 
fan of your proposal and Gildas additions.
