A Solution to rounding in Storyline – without using Javascript

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?
