Yoshiki,

Well, I did my homework (a bit too late). I googled "squeak-dev immediate
oop" and "squeak-dev immediate float". Lots of interesting reading,
extensive discussions on this topic. Apparently anything but 64bit IEEE
Floats (as Squeak Floats) is almost useless.

So, we probably won't have immediate Floats until we have 128 bits
machines...

Cheers,
Juan
