How to make accurate number abbreviations

Help and Feedback Scripting Support
#1

I’m trying to make some accurate abbreviations for my values for example.

local abbreviations = {
K = 1000,
M = 1000000,
B = 1000000000,
T = 1000000000000,
Qa = 1000000000000000,
Qi = 1000000000000000000
}

Then it shows as

4.26K
58.16K
1.73M
205.05B
155.10T
563.26Qa
7.19Qi

Please help me with this

The obvious approach would be to check if the absolute value of the number is between 0 and 999, then 1000 and 99999, and so on. However you can determine what power of a thousand the number is via logarithms.

Here’s an example of the latter:

local SuffixList = { "", "K", "M", "B", "T", "Q" }

local function Format(value, idp)
	local exp = math.floor(math.log(math.max(1, math.abs(value)), 1000))
	local suffix = SuffixList[1 + exp] or ("e+" .. exp)
	local norm = math.floor(value * ((10 ^ idp) / (1000 ^ exp))) / (10 ^ idp)

	return ("%." .. idp .. "f%s"):format(norm, suffix)
end

How can I turn a number to a shorter number (I don't know how to explain, click to understand :3)

How would I set a gui text using this? :thinking:

Set the Text property of the TextLabel/whatever GuiObject you’re using to the return value of the Format function.

label.Text = Format(12345, 2) -- 12.34K

So like label.Text = Format(ds.Value,2)?

It works thank you so much! <3
