1000 coins for 10 gems

1000/1000 = 1 * 10 gems

This is my formula but it seems to be more complicated with numbers such as 1038, 3828290

What’s the issue? You need to elaborate a lot on your post because I don’t really see a question aside from the title which isn’t explanatory enough.

#3

I want to know if there is a less complex method of converting currencies

#4

Divide by 100 instead of 1000? It shouldn’t matter anyways, this kind of thing could be done ~200 times a second and still not lag people

#5

How about if the number is 10,052

#6

What about it? Division in lua will return a float value, if you don’t want that you can do math.floor() on the value you divide.

#7

Well how do I know if the num is 1k,10k,100k

#8

I still don’t understand what you’re trying to ask. If you want to know whether a part is above a certain threshold you can just check that with val > threshold or val >= threshold if you want it to be inclusive

#9

I am talking about a currency converting system not a part

#10

Oops, made a typo, regardless the code snippets I sent are referring to numbers, there’s no way to determine if a part is greater than another part (what kind of metric would that be?)

#11

1000 coins for 10 gems ???

This text will be blurred

#12

I genuinely have no clue what you are talking about right now

#13

It literally says it in the title and I told u multiple conversions

#14

You were asking if the conversions were okay, right? They are correct, you can use >= or > to check for thresholds, and math.floor() if you don’t want float values.

#15

I think what he meant to say is only 1000 should be converted to 10, if its a 1002 then there’s a change which is 2.

Something like a while loop would work.

local currency = 1032
local gems = 0

while currency >= 1000 do
gems += 10
currency -= 1000
end

It think something like this should work:

local Leaderstats = game.Players.LocalPlayer.leaderstats.Points
local Leaderstats2 = game.Players.LocalPlayer.leaderstats.Gems

local NewValue = math.floor(Leaderstats.Value, 1000) -- Rounding there leaderstat down to the nearest 1000

local GemsAmount = NewValue / 100 -- Getting amount of gems to give.

Leaderstats.Value = Leaderstats.Value - NewValue
Leaderstats2.Value = Leaderstats2.Value + GemsAmount

I’m not entirely sure what you’re trying to achieve, but math.floor and the modulus operator should do the trick:

local function coinsToGems(coins: number)
	local gems = math.floor(coins / 100) -- Number of gems
	local coins = coins % 100 -- Leftover coins
	return gems, coins
end
