How to round the brightness value?
So i have this line of code that just sets the gui text to the brightness value of the flashlight. however it sets it to a odd 10 digit number (ex. 1.2000007312) i wish there was a way to round that number to 1.2, it works for the range value just fine but not for the brightness, how to fix?
1 | while true do |
2 | wait(0.5) |
3 | local Br = script.Parent.Parent.Parent.Parent.neon.SpotLight.Brightness |
4 | script.Parent.Text = ("B:"..Br) |
5 | end |

Hello! Hope your having a good day! You can do this by using string.format like so:
1 | local spotlight = script.Parent.Parent.Parent.Parent.neon.SpotLight |
2 | local decimalCount = 2 |
3 |
4 | while true do |
5 | local brightness = spotlight.Brightness |
6 | script.Parent.Text = string.format("%." .. (decimalCount) .. "f", brightness) |
7 | wait(.5) |
8 | end |
If the brightness was 12.1874 It would output "12.18" If you want to change the number of decimals change the decimalCount value!
EDIT: Make sure you have your script as a LocalScript in your GuiElement, otherwise it won't work.
Here are my results and setup:

Math.floor(number*10)/10 any good?

You should find some success with the following code:
1 | function truncate(num, digits) |
2 | local mult = 10^(digits) |
3 | return math.modf(num*mult)/mult |
4 | end |
Give it a number, in this case brightness, and the amount of decimals you want to keep, in this case 1, and it'll return the number with a truncated decimal.
eg. truncate(1.2000007312, 1) --1.2
1 | function round(num, numDecimalPlaces) |
2 | local mult = 10^(numDecimalPlaces or 0) |
3 | return math.floor(num * mult + 0.5) / mult |
4 | end |
5 |
6 | round(brightness) |
