[PD] expr pow prob.

[Galen Elfert]

Hello PDple

I've been learning to use PD over the last couple of months, and I've 
been very happy with the way it's all turning out. The documentation is 
generally top-notch.
Nevertheless, I have quite a few questions. I'll just pose one for now 
though, which I hope will be easy to straighten out.
For some reason the pow() function in expr only returns integers for 
me, lopping off the decimal point. I haven't seen anything that would 
indicate that this is the expected behavior. Does anyone know why this 
might be?

Thank you,
Galen
