  Count-up expression

  Posted by Deniz Nasif on October 25, 2011 at 5:59 pm

  Hi,

  I currently have numbers counting up using the following expression:

  beginTime = 0;
  endTime = 15.02;
  startVal = 0.00;
  endVal = 15;

  Math.round(linear(time,beginTime,endTime,startVal,endVal))

  However, I want to add decimals to it, so it basically says 0.00. Any help would be greatly appreciated.
  Many thanks in advance.

  If you just want to add “.00” to the result, change the last line to this:

  Math.round(linear(time,beginTime,endTime,startVal,endVal)) + “.00”

  If you actually want two decimal places in the result, you would change it to this:

  linear(time,beginTime,endTime,startVal,endVal).toFixed(2)

  hey, first post here so be gentle. 🙂

  I wan’t to get the same effect only i need my final number to have “.” between digits.

  Specifically I need my count to start from €0 and get to €50.000.000

  I have this expression (which I found here on another amazing thread):

  beginTime = 0;
  endTime = 5;
  startVal = 100;
  endVal = 1200000,00;

  “€” + Math.round(linear(time,beginTime,endTime,startVal,endVal))

  How can I get it to work with “.” in between ? Thank you so much in advance

  beginTime = 0;
endTime = 5;
startVal = 100;
endVal = 1200000,00;

  This should work:

  
beginTime = 0;
endTime = 5;
startVal = 0;
endVal = 50000000;

  s = "" + Math.round(linear(time, beginTime, endTime, startVal, endVal))
prefix = "€";
outStr = s.substr(-s.length, (s.length-1)%3 +1);
for (i = Math.floor((s.length-1)/3); i > 0; i--){
outStr += "." + s.substr(-i*3,3);
}
"€" + outStr

  worked like a charm Dan, thank you. Now to add ,88 at the end? (or any other decimal for that matter?)

  I’m guessing this isn’t really what you want, but you could change the last line to:

  “€” + outStr +”,88″

  If what you really want is the fractional part of the count rounded to two digits, I really wish you had mentioned that to start with, before I ripped all that stuff out of the expression.
