I think that without log2 there's no way to get (x + 1) from (x). <pause to write, debug, compile and run a program> Well, I think it's not possible to get x++ using just those keys. I tried to generate 10000 numbers using those functions [except arc-hyperbolic stuff, that are not functions in M$ Visual C] and I didn't even get number _3_. > >Pi is ln(square(square(exp(arctan(exp(0)))))) >though there may be quicker ways to get it. > Pi = arccos(-1) too, so Pi = arccos(ln(1/(exp(exp(0))))) Alberto Monteiro
