A Solution to rounding in Storyline – without using Javascript

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.
