Frequently, it is nice to convert numbers to strings in actionscript 3. For example, this will correct the error — 1067: Implicit coercion of a value of type Number to an unrelated type String.

In my neverending journey to teach myself actionscript, I have once again started pounding through some code.

In short to convert a number to a string, use the following construct:

text = String(number);

If you try to avoid this step, it’ll throw the following error…

1067: Implicit coercion of a value of type Number to an unrelated type String.

Here is some example code that will throw the error:


var time:Date= new Date();
var txt:String;
txt = time.milliseconds;


This code works correctly:


var time:Date= new Date();
var txt:String;
txt = String(time.milliseconds);

   how about if I have a number, i.e.: 23 and I want to converted it to the string “0023″ (with 4 digits i.e.)?…

   same problem
   I’m getting a number from an XML, looks like 123,456,78
   i then myString.split(“,”).join(“”);
   gives me “12345678″
   now I want to use it in some math,
   i tried Number(myString);
   that just gives me the error above

   How to do whith that?:

   var D:String;
   D = String(b * b – 4 * a * c);

   thats cool man, but how would you know wich class to add so you can use the “string()” converter

5. jenny said on May 22, 2009

   or you could use (time.milliseconds).toString()

   @ littleman80
   var num:Number = 23;
   var StringConverted:String = “00″+String(num);
   trace(StringConverted);

   @justin
   to convert a string to number use this
   var TheString:String = “12345678″;
   var TheNumber:Number = parseInt(TheString);
   trace(TheNumber * 2) // by using * u can test that its really a number

    Nice and simple….

    var myNumber:Number = 33;
    var myString = myNumber + “”;

    No functions. No Mess :-)

    i.e. does NOT mean ‘for example’.  Be a big man and learn e.g.

    No help at all. I converted the amount of the instore currency to a string and all I got was deied. Heres the code:
    credits.text=MochiCoins.inventory.storecredits+”"
    credits is the dynamic text box
    MochiCoins.inventory.storecredits is the path to the store credits via mochi media

    Still the same problem, my code is:

    var five:Number = 5;
    var six:Number = 6;
    var sum:Number = Number(five)+ Number(six);
    trace(suma);

17. ape23 said on August 30, 2011

    shouldnt it say:
    var sum:Number = five + six;
    ?
