Evaluating a user's math function?

[Lemures]

I have to write a small program for a class, and ultimately what I need it to do is to evaluate a user's function at certain values. The functions won't be terribly complex. For example, I want an InputBox to pop up, and the user would input, say, "3(x^2)-4x+6". Then my program would evaluate it at certain values (x=0, x=1, x=2, etc) and do something with the results.

Is there an easy way to have the user input a string and have autoit convert it into a function that can be evaluated?

Eval()

Ah. I ended up using Execute(). I had forgotten that that existed. Thanks!

This may be of interest to you. It's more robust and would be better in the long run to write a parser rather than rely on AutoIt's dynamic execution functions.
