Input Text in Math

[rigelj]

Is it possible to use input text in math equations?

[abeall]

Yes.

var inputNum:Number = Number(myInputText.text);
if(isNaN(inputNum)){
    // user input invalid number!
}else{
    // do math as usual, ex:
    inputNum * 2;
}

You will probably want to set the input text restrict to just numbers, and dot if you want decimals.

If you want to parse out a full expression from input text, that's a much trickier subject.
