Is there a way to choose what decimal point math.floor/ceil round to? Like make it round to the 100th or 1000th instead?

Can you choose what decimal math.floor and math.ceil round to?

No, but you can do some fancy math with powers of ten to get that behavior:
function ceilBase(num, decimals)
if not decimals then decimals = 0 end
local pow = 10^decimals
num = num*pow
num = math.ceil(num)
num = num/pow
return num
end
And the same for math.floor.

A simple method, if you're comfortable with the math, is to simply say "math.ceil(num * 10) / 10" (for rounding to a single decimal point)
