Is it Possible to Print a Rounded Value?

local a = script.Parent

for i=1, 10 do
    a.Transparency = a.Transparency+0.1
    wait(0.2)
end

print("The transparency of the brick is " .. tostring(a.Transparency))

Output: The transparency of the brick is 1.0000001192093

Is it possible to tell the computer to round the value rather than have all these significant figures?

doesnt math.floor() have something to do with that? iFireLazer 35 — 8y

also i've never had this problem, but i've never used tostring, so maybe remove just tostring and see what happens. iFireLazer 35 — 8y

You're right. I just searched the wiki. There's math.floor() and math.ceil(). Is there a function that rounds based on the following significant figure though rather than to the highest integer or lowest integer? RAYAN1565 691 — 8y

Using math.floor() you can round Down whatever you wish to inside the parenthesis.

There is a simple method to allow it to round to the nearest whole number though. Simply add .5 to whatever you wish to round up within the math.floor method.

Example:

print(math.floor(2.2 + .5)) -- This should print 2

print(math.floor(2.8 + .5)) -- This should print 3

Using your script:

local a = script.Parent

for i=1, 10 do
    a.Transparency = a.Transparency+0.1
    wait(0.2)
end

print("The transparency of the brick is " .. tostring(math.floor(a.Transparency + .5)))

Let me know if you have any other questions!

Makes sense. Also you can use math.ceil() to round up. Thanks for the explanation and link! RAYAN1565 691 — 8y
