A Solution to rounding in Storyline – without using Javascript

I'll try this not for quizzing but simply wanting to display whole % such as % of ee's in one location or another - quizzing must already be displaying %s not in decimal form, since, when working with variables simply on a silde or layer, you must divide by 100,000 & multiply by 10,000,000 to get the correct result.

Don't suppose there's a solution to formatting with commas? for ex: I want the number value (can't be text) of 31000 to display 31,000.
