Also, I don’t know how math.round works behind the scenes, but I believe you can also do math.floor(number+0.5) This way, when the number’s decimal is larger or equal to/than 0.5, it’ll round to the larger number, and when smaller, to the same number without (the Integer). Both ways (math.round then floor, or floor+0.5) should work.
Here’s a quicker way of rounding in cases where performance is the must: Add 0.5 to n, putting it over the bar if it’s already >0.5, then subtract the “remainder” decimal from it. The simplest way to round would be by using math.round (displayed below). return math.round(number * 10^decimalPlaces) * 10^-decimalPlaces.
If the number is 4 or below, keep the number the same. If the number is 5 or more, add 1 to the overall number and remove everything right to the decimal point. I don’t know exactly how this would be implemented, but it could potentially work. You don’t need to round or floor the number for this.
Yes that does work, however math.round is rounding (either doing floor or ceil depending on the decimals) which might have a performance cost and possibly floating point jank, but overall it seems to work the same. In summary: Using Luau: math.round(number*100)/100 or math.floor(value*100)/100
number = math.round(number / 10) * 10. end. 1 Like. D0RYU (nici) June 3, 2021, 4:05pm #3. math.ceil will round up every time. math.floor will round down every time. math.round will round normally like how 5 goes up but 4 goes down. Philipceo90 (Phil) June 3, 2021, 4:06pm #4. if the number is 15 or 20 or 30 then it stays the same, if its 12 it ...
For example, I got a ridiculously long decimal like: 0.01943638963 I tried math.floor but that gives me: 0 or math.ceil which gives: 1 OR math.round: 0 so how do I round a decimal to a specific number of decimal places?
using just a little a bit of math you can move the decimal forward and later move it back, for exampel. local x = 0.05555. local y = x * 100 --will move the decimal back two steps (or the amount of zeros you add) y = math.round(y) x = y / 100 --will move the decimal forward two steps (again the amount of zeros) print (x) -- 0.05. 1 Like.
This is an all-in-one number formatting module designed for displaying numbers in a more user friendly way. It is not designed for internationlization but there are enough features so if you want a basic internationlization (no unit formatting, RBNF or something like that but a basic decimal comma and point change with Symbols but keep in mind that this is not documented here), it’ll work ...
You can write your topic however you want, but you need to answer these questions: i want to make my meter Counter Round the numbers i used math.Round, math.ceil, math.floor but result is still the same i tried looking into other dev forum posts, dev hub, Youtube e.t.c nothing helped Video Link: [Screen Capture 20.07.2023, 23.04.27] while wait() do local player = game.Players.LocalPlayer local ...
number = math.floor(number * 10) / 10. This takes the number, multiplies it by 10, floors it, then divides it by 10. I had round, but 29.9999 would round to 30. Floor basically truncates the fractional part by returning the biggest integer equal to or smaller than the number you give it.
