I found a way to round numbers in Storyline without using Javascript. The challenge was to show whole percentage numbers from calculated decimal numbers (i.e. 33% for 1/3 and 67% for 2/3). Searching through the forums, all I could find was Javascript solutions and suggestions to submit a feature request. Not happy with either of these answers, I continued to play around.
I found that Storyline only holds 7 digits past the decimal place, and the 7th digit is rounded. So to get a rounded decimal (percentage) as a whole number, divide by 100,000, and then multiply by 10,000,000.
For example:
2 / 3 = 0.6666667 (rounded at the 7th position by Storyline)
0.6666667 / 100,000 = .000006666667 (which is rounded to 0.0000067)
0.0000067 * 10,000,000 = 67
Now we have our rounded 67% from 2/3
You should be able to apply this to any number you want to round. Divide and then multiply by a multiple of 10 that is large enough to push the number you want to round to the 7th position past the decimal (i.e. 13,567 / 10,000,000,000 * 10,000,000,000 = 14,000)
Hello everyone,
I have some great news to share! We just released another update for Storyline 360. In Update 112, we’ve included essential fixes and new features. One of the new features we’ve included is:
- Simplify reporting with a built-in option that rounds quiz scores to whole numbers.
Launch the Articulate 360 desktop app on your computer to take advantage of this update, and click the Update button next to Storyline 360. You’ll find our step-by-step instructions here.
Please let me know if you need additional help.

This method only works in Storyline 2. Storyline 3 holds much more digits. I divided number by 1e+308 (max) and then multipled by 1e+308 and the result was the same as source number.
Hi!
Old but usefull thread. I´m trying to use it in Storyline 360 and it seems that it´s not working anymore. The number rounds up in storyline 2 but the same source file opened in 360 doesn´t work (it always shows two decimal numbers). Is there another workarround? Thanks!
I'm in the same boat as Miriam - In need of this, but it doesn't work in SL3 either - Anyone have any miracles?
As long as you are not using the mobile player, JavaScript is your friend for rounding.
StoryLine 3/360 now support an infinitely long decimal making the old math round solution obsolete.
A colleague shared this very helpful tip that finally solved the issue for me! I created a Storyline number variable called RoundedScore, which I set equal to the Results.ScorePercent as the results slide timeline begins. Then I execute this Javascript:
var player = GetPlayer();
var score = player.GetVar("RoundedScore");
player.SetVar("RoundedScore", Math.round(score));Finally, I changed the "%Results'ScorePercent%%" text on the results slide to "%RoundedScore%%", and it works in Storyline 3! I hope this helps others who want to round the percentage in Storyline 3.

Hey Mike, I tried your method in Storyline 3 and it didn't seem to work for me. Do you execute that Javascript when the timeline starts are is the trigger set up to go off at some other point?
I've tried this method in Storyline 3, and it doesn't seem to work. I still get a percentage down to the hundredths. I've even taken the divide/multiply operation to the maximum number of characters to no avail.
I tried copying some Javascript as well. I created a trigger to execute the following Javascript command: Math.round(Results.ScorePercent);
This did not work, either.
Any suggestions?
Does anyone have specific screen shots on how to do round the percentage? I really can't seem to work out how to do this.
Thanks!
This works fine in flash version but not in html5 version
Why couldn't you perform your math functions followed by the division and multiplication at the end to get the whole number. You could also use a condition to say if the answer is >10, you subtract one of the 0's, still allowing you to use the program without JS.
ex. answerNum / 100000 x 10000000 if answerNum<10
then another trigger that says answerNum / 10000 x 10000000 if answerNum>=10
The concept should be true. I'd have to actually play with the numbers to make it work exactly, but these kinds of triggers are definitely doable.
Wow. I was skeptical, but this worked great! Thank you soooooooo much.
Hi,
As someone who doesn't really know much about Javascript, I'm trying to figure out how to solve a problem I'm having. In our course, we have a variable that we are displaying on each page to show the % complete. We did the divide by 10,000,000 then multiply by 10,000,000 and it's working fine non-mac devices. However Macs are still displaying the two decimal places and we want to get rid of that. So, I tried to add this JS after my % visited variable is calculated and it's not working.
Here is what I added:
var player = GetPlayer();
var numValue = GblScreensVisitedPercentage
var JSRoundedNum = numValue.toFixed(1);
player.SetVar("RoundedNum",JSRoundedNum);Any thoughts would be greatly appreciated!
Please does anyone know if the number of decimal places stored has changed? I have published a course in Storyline 1 before and using the dividing/multiply method and all worked fine. Have now published from Storyline 2 and I get the two decimal places again. Also, I am now using HTML5 output. Thanks
