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)
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.
This works fine in flash version but not in html5 version
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!
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?
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.
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.
I have tried the trick of Terry and Tom but the math are incorrect. I am not using this with a test score but with a slider, and I would like the slider to display just non decimal values but allow the slider to move in 10th of decimals.
Why is this the "rounded" value incorrect ?
Is this still working in 360?
Some previous SL2 conversions to 360 aren't showing as rounded and starting from scratch comes up without rounding as well.
I does not work in 360. See my solution above for a floor function that works in 360.
I can't get this to work. I used the file that Tom uploaded four years ago (thanks Tom)! Wonder why this is still not automatic.
Anyway, maybe it's not working because I have two quizzes in my course so I have two results slides + I also have a final results slide.
I'm not as technically inclined as most of you so I just literally copy everything that Tom did in his file. I am unable to troubleshoot with my low skill levels.
Can anyone help me figure out why it isn't working? Does it have to do with the fact that I have 3 results slides? Should one of the triggers be altered? Do I need 3 variables...1 for each results slide? Everything I've tried has failed.
Thanks!
Hello Mitch and Lauren,
Mitch, thank you for the great workaround! Lauren, thank you for explaining how to keep the score at 100 vs. 99.
I am still trying to grasp how this workaround actually works... Now I'm getting 1% if I get all of the answers wrong.
Did anyone else run into this? What additional trigger am I missing to prevent this from happening?
Thank you again!
