Ummm...Ok, I really have to say this: What the hell are you talking
about? :)
The FPU in the pentium HAS EIGHT registers... so, comparing it to an FPU
with
8 registers is like comparing apples and apples...

Wrong again... :)  Well, the simultaneous sin and cos is there, and I am
not too sure about the hyperbolics (I've never needed it!)

Go to http://www.x86.org and have a look around... :)
