How to get the first number of a big number in AS3

Okay so what I'm trying to do in AS3 is get the first number of a big number.

For example if I have a variable named TesterNum and it equals to 6:4204542 I'm trying to get the first number of the variable, which is 6.

I'm trying to create a code that says:

var TesterNum:Number = 6:4204542;
if(TheFirstNumberOfTesterNum == 6){
trace("Works");
}

What's the code to get the first number of a variable?

Use chatAt(); method like this:

var TesterNum:Number = 6:4204542;
var control:String = TesterNum.charAt(0);
trace(control);
//it give you 6

I'm going to assume that your variable is a String and not a Number (because of the colon which would cause your code in your question to throw a compiler error).

In that case, there are a few ways to do the same thing:

  1. Use parseInt - which will grab the whole number prior to anything that is not a number, so in your case, anything before the colon. This will be the easiest if your. first number can be more than one digit. 

     var TesterNum = "6:4204542";
 if(parseInt(TesterNum) == 6) //true

  2. Use charAt, which get's the character at the specified index, then convert that character to an integer. This method is alright if you only need one digit ever.

    var TesterNum = "6:4204542";
if(int(TesterNum.charAt(0)) == 6) //true

  3. Use substrto get all characters before the colon, then convert that to a Number or integer. This is exactly the same result as method #1.

    int(TesterNum.substr(0, TesterNum.indexOf(":"))) == 6
