Is there a way to take a AnsiString like:

AnsiString formula;
formula = "(4*5)+(12/3)";

and changing that formula to a float value without parsing the string.

For instance I'm using a TEdit control the user is inputing a formula or just a chain of like: 1+2/3

Thanks

You should use a commercial math interpreter library or component. A good place to start looking is here:
