Use this function:

//set number to 2 decimal places
//You can set this anywhere in your timeline and use as you need anywhere in your movie.

Math.__proto__.dec2 = function (num){

valor = String (Math.round(num * 100) / 100);
dot = valor.indexOf(".");

if(dot == -1){
valor += ".0";
temp = valor.split(".");
addDecimals = 2 - temp[1].length;
for(i=1; i<= addDecimals; i++){
valor += "0";
return valor;


a = 0.5;
b = 0.8;
z = Math.dec2(5);//if you trace thism, z will display "5.00"
z = Math.dec2(a + b);//if you trace thism, z will display "1.30"

PN: I have not written this code i found it in
