Normal 0 false false false oNotPromoteQF /> EN-US X-NONE X-NONE 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)

Thanks for the tip. I needed to have rounded off percentages for my project. This really should be an option that can be set in the quiz options. I posted a feature request. I am including a zipped up sample of the Articulate Storyline file here for others to see how this was set up. There is also a "Instructions" PDF file included with some screenshots of variables setup. My quiz here uses a number of question banks so the questions are randomized. To sum up what happens is per previous instructions by Terri and others I have created a few triggers that divide and then multiply the quiz results Percentage score by 10000000. It does this to push the score percentage past the Seven digits limit decimal place.

Since this does not work in Storyline 360, I found a very easy way to implement a floor flunction in Storyline 360 without using Javascript. EDIT: Corrected for edge cases and much simplified! Also attached an updated screenshot. Corrected Steps: Create one variable, floorScore, and initialize to 0 Results Slide triggers: Set floorScore equal to 100 when the timeline starts Subtract 1 from floorScore when floorScore changes if floorScore is greater than Results.ScorePercent And that is it! -------------------------------------------- Old (incorrect) version below. Edit 4/17/2019: I have removed the incorrect version to avoid confusion.

Divide by 10.000,000 and then multiply by the same. For those who want the math logic behind this answer, 42.85 / 10,000,000 = 0.0000043 in articulate (dividing by 10,000,000 moves the decimal place 7 places to the left and the 7th decimal position gets rounded) 0.0000043 * 10,000,000 = 43.0 (multiplying by 10,000,000 moves the decimal 7 places to the right resulting in a whole number)

I ran into a similar issue and I didn't want to spend the time to make this edit since I only had a 3 question quiz so I found a really good alternative! All I did was change the question scores from the defaulted 10pts (2 to 33pts and 1 to 34pts) and then changed the results display from %Results.ScorePercent% to %Results.ScorePoints%. That resulted in making the results rounded in less than a minute!

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.

A Solution to rounding in Storyline – without using Javascript

Can anyone help me find a fix to my problem.

I have been happily using the rounding up solution posted above (great fix BTW) but I've run into an issue.

I have a screen that calculates stuff. The main calculation is taking a number and dividing it by 30%. This solution has worked a treat until we entered the value 30.

30% of 30 = 9 but this solution because of the divide / multiply scenario returns the incorrect value of 10.

So whilst rounding up is fab in most situations I need a solution that allow me to also return the correct value?

NE1?

  @Chris Elkin - can you share any part of your file/screens/triggers? And can you clarify if you are multiplying by 30% or dividing by 30%?
  
  30 multiplied by .30 = 9
  
  30 divided by .30 = 100 (if you're using this formula and rounding to two digiits, it would explain why the result returned was 10)
  
  Hope to hear from you soon.

Sorry Diane, confusing myself - my post should have ready multiply by 30%

I have included screenshot with triggers:

Desperately need to get the result of 9 rather than 10 but also round up decimal numbers...

It will always show 10 because of the way Storyline calculates to 7 decimal places, you are turning the number into 8 decimal places which rounds up to 0.0000001, this may be where you need to use javascript instead.

Cheers Phil, IU thought this might the case!!!!

So has anyone got an example of a JS rounding script?

    I tried applying this JavaScript and it doesn't seem to work. I have an answer that shows as (i.e.) 10.454240362 and I want it to round up to 10.45
    
    How can I apply a variable/JavaScript to make this work?
    
    Thanks

Hi - thanks for this script.

I've added the additional line to the code:

var numTimes = numValue * 0.3;

and now I don't get a rounded whole number with every calculation

e.g.

enter 100 returns 30 - cool

enter 30 returns 9 - cool

enter 54 returns 16.2 - ??? would like it to round unto 17

NE1?

_________________________________________________________________________

var numValue = player.GetVar("howMany");

var numTimes = numValue * 0.3;

var JSRoundedNum = numTimes.toFixed(1);

player.SetVar("total",JSRoundedNum);

  Shouldn't it be .toFixed(2) for 2 decimal places

  Well I should read the post change to a 0 should give an integer

I ended up just creating the variables and dividing then multiplying them. It worked like a charm.

All you seriously have to do is delete the first set - %Results.ScorePercent%% - and then remove the parentheses and then all you get is the total amount of points. Hope this helps! Allison

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

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!

Wow. I was skeptical, but this worked great! Thank you soooooooo much.
