Basically how do I turn 9.12761656 to 9.12? I tried using math.floor but it turns it into an integer. Thanks!

One way would be to multiply it by 100, floor that, then divide it by 100.
9.12761656 * 100 = 912.761656
floor of 912.761656 = 912
912 / 100 = 9.12
Hope this helped
I've seen this question before. Here's a quick problem-solver. I've created a function that rounds a long decimal into a short decimal:
local function decimalRound(num,round)
-- Checking if both variables are valid numbers, otherwise throws an error.
assert(tonumber(num),"Variable num is not a number.")
assert(tonumber(round),"Variable round is not a number.")
-- Calculations
local result = num
local roundNum = 10^round
result *= roundNum
result = math.floor(result)
result /= roundNum
-- Return the "result" variable
return result
end
Example of using decimalRound():
local x = decimalRound(9.12761656,2)
print(x)
The following example would return:
9.12
No problem, from Canada. :)

what does assert mean??

^ whenever the first parameter of assert is false or nil, it errors the second parameter

I've created a function for this, so you are right too, but I have a feeling mine is easier to use.
