A Solution to rounding in Storyline – without using Javascript

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 7^th 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 7^th 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)
