hi,
i´m working on preloader and want to convert seconds from "time elapsed" and "time remaining" in minutes. Anyone got idea how can i make, let´s say 200 seconds to be 3´:33´´ ???.
thanks

I'm sure their is an easier way of doing it, but this should work:
Code:
num=200;
minutes=Math.round(num/60);
sec=num(minutes*60);
trace("time: "+minutes+":"+sec);
//time: 3:20

thanks for quick reply I´ll try that now, if I came up with something else i´ll post it.

OK ! this works, i only used Math.floor instead Math.round because in preloading connection speed isn´t constant and i was getting some "50" results for seconds. Thanks again...and if you are still with me...i have connection speed detection in preloader and when it is let´s say 2.00 kb/s it becomes just 2 in output, but i want it to be 2.00 so that numbers don´t jump left and right. Example, for seconds i used this:
if (seconds1< 10){
seconds = "0"+seconds1;
}
else{
seconds = seconds1;
}
So the 9 sec becomes 09, and 24 stays 24...
Any ideas ???

//format a number into specified number of decimal places
Math.formatDecimals = function (num, digits) {
//if no decimal places needed, we're done
if (digits <= 0) {
return Math.round(num);
}
//round the number to specified decimal places
//e.g. 12.3456 to 3 digits (12.346) > mult. by 1000, round, div. by 1000
var tenToPower = Math.pow(10, digits);
var cropped = String(Math.round(num * tenToPower) / tenToPower);
//add decimal point if missing
if (cropped.indexOf(".") == 1) {
cropped += ".0"; //e.g. 5 > 5.0 (at least one zero is needed)
}
//finally, force correct number of zeroes; add some if necessary
var halves = cropped.split("."); //grab numbers to the right of the decimal
//compare digits in right half of string to digits wanted
var zerosNeeded = digits  halves[1].length; //number of zeros to add
for (var i=1; i <= zerosNeeded; i++) {
cropped += "0";
}
return(cropped);

my_num2 = Math.formatDecimals(1.1,2);
trace (my_num2);


Ok, i´m lost and confused. I can´t get it right. Do i need all this code you give me? I tried using some parts but it doesn´t work.
This is what i have:
var loadedd = Math.floor(this.getBytesLoaded()/1024);
var elapsed = Math.round(getTimer()/1000);
//dividing this 2 var gives me connection speed
var speed = ((Math.round((loadedd/elapsed)*100))/100);
When var speed is 2 kb/s i want it to be 2.00 kb/s , or when it is 1.7 kb/s i want it to be 1.70 kb/s. What i´m doing wrong with all that code you post ??? I don´t think i should use all of it ....or am I ????
thanks in advance

Yes, this is a function, and you should be using all of it...
Put this in your first frame on the main timeline:
//format a number into specified number of decimal places
Math.formatDecimals = function (num, digits) {
//if no decimal places needed, we're done
if (digits <= 0) {
return Math.round(num);
}
//round the number to specified decimal places
//e.g. 12.3456 to 3 digits (12.346) > mult. by 1000, round, div. by 1000
var tenToPower = Math.pow(10, digits);
var cropped = String(Math.round(num * tenToPower) / tenToPower);
//add decimal point if missing
if (cropped.indexOf(".") == 1) {
cropped += ".0"; //e.g. 5 > 5.0 (at least one zero is needed)
}
//finally, force correct number of zeroes; add some if necessary
var halves = cropped.split("."); //grab numbers to the right of the decimal
//compare digits in right half of string to digits wanted
var zerosNeeded = digits  halves[1].length; //number of zeros to add
for (var i=1; i <= zerosNeeded; i++) {
cropped += "0";
}
return(cropped);

Then after your line var speed = ((Math.round((loadedd/elapsed)*100))/100);
run your speed variable through it by adding the following:
cor_speed = Math.formatDecimals(speed,2);
Change the variable of the speed display textfield to cor_speed, although using this might still work:
speed = Math.formatDecimals(speed,2);

it works !!! thank you man this is great!
take care
