I'm interested in building node(s) for various rounding functions. This is currently a "round" node - it rounds any decimal places to become whole numbers using the most common method of rounding up if the decimal is .5 or higher and rounding down if the decimal is less than .5. I'd like to add these additional options: "round up" "round down", and a variable round function (ie. round to nearest 10 or 100 or 1000 etc.).
My problem is that I don't know how to "Get" individual digits from multi-digit numbers. Anybody know how the out-of-the-box Round function did this?
