[flasher] Evaluating/converting Formulas??

[Glen Rhodes]

Hey everyone,


What I'd like to do is have the user input a formula into a text box... like

"3 + x"


And then, have Flash calculate the answer to that, depending on different

values for x.


So, the variable


formula = "3 + x";

x = 9;


answer = the formula, evaluated.


The key is, I'd like the user to be able to enter ANY formula.. like "(3 + x

* (1 / x)) / 5", etc..  And, depending upon what "x" is, the answer will be

different.


So, the user MUST be able to type in their OWN formulas.  So, I'm trying to

essentially EVALUATE a string of TEXT, as if it were an equation in a

number.


In Flash,

formula = "3 + x";    is not the same as

formula = 3 + x;


I want to convert the former into the latter.


Any ideas?
