Not now. It was in the beta version of this script, but I haven't finished it.

fixed

>>pow(x,2) works
pow(2,x) and pow(x,x) also works perfectly

>> log(x) works for minX = 0
I set "x=minx+1/10e8" because of "Unexpected condition error" with y=1/x function. For example, y=x/0 correctly works (infinity message appears). I don't know why..

>>If a version were created for a U parameter, nested with a V parameter, it might do 3d curves ?
Yes, I think so.
