Hi, I have a very simple question. I wnated to do a ^ (power) on the fpu but the only function that has SOMETHING to do with powers is fscale but it only does a add or sub on the exponent. So how DO I perform a ^ (power) on the FPU? any one? EOT MR Master

hopefully this is what you are talking about..

Try the function called "pow".

--> st(0) = 2^st(0) - 1

hummm.....

Syntax: I was more or less hinting towards asm and not c.... but thanx any way.

Ga: I know what this does and you can also use fscale. but this is like 2^st(0), and I was hoping to find something that would do

st(0) ^ st(1)

I guess I'll just rip apart a vbdos lib for the pow function....

x^y = a^(loga(x)*y)

so x^y = 2^(log2(x)*y)

and you get st(1)*log2(st(0)) with
fyl2x
