There is a Unix command called "bc" that can parse and evaluate
expressions. You con create an NSTask or something running "bc", feed
your expression into the task's stdin, and read the result on its
stdout.

Hi,
I read a string from a file.
This string contains:
@"x * y"
I already have two global int variables called "x" and "y".
Now I would like to get the product of x and y.
How should I do?
Best Regards
