Count with decimal place "dynamic text" AS3

Question

This is my 2-part question. My understanding is small so "beer" with me.

This example counts from 1-100. I want the decimal keep counting to ten over-and over. (a.)How do I loop the decimal? 1-10 over-and-over. (b.)How to I get the whole and decimal value on the same dynamic text field?

THING
"It's a counter with whole and decimal values"
-text filed receive string of whole number and decimal place
-decimal fast, whole number slow

CODE

/*I made two text fields, change the names and values, but the values didn't
respond properly. 1000 = 1 sec and 100 = 1/10th or a second. The whole thing changed.*/
//working code

var timer:Timer = new Timer(1000, 100);
timer.addEventListener(TimerEvent.TIMER, countdown);
timer.start();
function countdown(event:TimerEvent) {
    myText.text = String(0 + timer.currentCount);
}

IDEAS
(a.)
//RESET START
function countdown($evt:TimerEvent):void {
timer.reset();
timer.start();

VERBOSE EXAMPLE
if Number's less than 11, do it again

(b.)
//STRING
var time:String =whole + ":" + decimal;

time_txt.text = countdown;

UNEXPECTED PROBLEMS
-changing values (1000, 100) didn't work "affects the other number"
-I don't know how I'm going to add velocity to something in the timer class "an other post"

THE DECIMALS STAY IN THEIR PLACE

//CA, NC, LONDON
var timer:Timer = new Timer(10);  
var count:int = 0; //start at -1 if you want the first decimal to be 0  
var fcount:int = 0; 

timer.addEventListener(TimerEvent.TIMER, incrementCounter);  
timer.start();  


function incrementCounter(event:TimerEvent) { 
  count++; 

  var whole_value:int = int(count / 100); //change value
  var tenths:int = int(count / 10) % 10;  
  var hundredths:int = int(count) % 10;  

  mytext.text = whole_value + " : " + tenths + hundredths; 
}

CRITERIA "I forgot to include 2/10/10"
WHOLES
X 10 multiples

DECIMALS
tenths dec = 10% of ones
hundreds dec = 10% of tenths dec

Answer 1

It's probably better to use your own count variable instead of the one from the timer. You want something like the following. Every time the timer ticks the count will update by one. The "%" is the modulo operator.

var timer:Timer = new Timer(1000);
var count:int = 0; //start at -1 if you want the first decimal to be 0

timer.addEventListener(TimerEvent.TIMER, incrementCounter);
timer.start();


function incrementCounter(event:TimerEvent) {
  count++;

  var whole_value:int = int(count / 10);
  var decimal_value:int = count % 10; 
  mytext.text = whole_value + " : " + decimal_value;
}

Answer 2

var timer:Timer = new Timer(100);
timer.addEventListener(TimerEvent.TIMER, countdown);
timer.start();
var time = 2000;
function countdown(event:TimerEvent) {
 time -= 1;
 var seconds = int(time/10);
 var tenths = int(time - seconds*10);
 time_txt.text = seconds + " : " + tenths;
    if (time == 0) {
        timer.stop();
    }
}

To adapt Nathan's answer for 100/ths you could do something like this:

function incrementCounter(event:TimerEvent) {
  count++;

  var whole_value:int = int(count / 100);
  var tenths:int = int(count / 10) % 10; 
  var hundredths:int = int(count) % 10; 

  mytext.text = whole_value + " : " + tenths + hundredths;
}
