This question already has an answer here:

math.round ?

I want to use math.floor() but it rounds to real numbers. Is there a way I can set it to round tenths not rounding it to real numbers?

You first multiply your number by 10 round it, then divide by ten again. :)

I once created a handy function for this;

function Round(Num, Decimals)
    return math.floor((Num)*(10 ^Decimals) + 0.5)/(10^Decimals)
end

In your case, use

Round(x, 1) where x is your number.

Please ask if you would like an explanation :)

This won't work exactly as expected for negative numbers, by the way. adark 5487 — 10y
