This can be done with integers, if we define some 'human big number
format', or so. But I think that FP/FPE is more generic problem,
because of modularity of grub.

It seems to me that some combinations (like grub with FP emul, and
module with FP instructions) may not work. I think, there should be
left (compiletime) decision on user if she want to use FP emul. So
I'm voting for having possibility to use FP instructions, at least
on platforms where it is possible easily.
