Rounding

[naftali]

I found myself wanting to round to numbers of greater accuracy than whole numbers (4.325 rounding to 4.33 instead of 4) so I wrote a pair of functions to do that!

Code: Select all

function roundUp(number, places)
	return math.ceil(number * math.pow(10,places)) / math.pow(10,places)
end

function roundDown(number, places)
	return math.floor(number * math.pow(10,places)) / math.pow(10,places)
end

Not sure if there's a way to make these faster using something other than math.pow, but I couldn't think of an easy way to code it. Enjoy!

Personally, if I want a number rounded and printed, I use string.format("%0.2f",number) to get it nicely rounded to two decimals. That can't do round up/down though, I think.
