How can you deal with large numbers?
Hello, i have the following issue.
my game allows player to get a very large score having 10 digits in the leader board looks ridicules so i came up with the following solution
if n > 1000 then
return math.floor(n / 1000) .. "K"
elseif n > 1000000 then
return math.floor(n / 1000000) .. "M"
else
return n .. ""
end
the issue is where should i place the statement?
should i make it into a function then call it every time a script changes to score value? or is there a way to run something everytime a value is changed?

You can make a NumberValue (an actual physical object) that contains the player's score and use the the Changed event on that. I don't really use dataStore or leaderboards much so I couldn't tell you exacty where to store the NumberValue, that's up to you. Trew86 175 — 5y

Slightly off topic but you need to check for n > 1000000 first instead of n > 1000 because if the score is 100000000 for example it still uses K instead of M. Rheines 661 — 5y

If you store the number in a IntValue object then you can create a listener for when the IntValues value changes
local intvalue = Instance.new("IntValue")
scoreboardCalculations = function()
if n > 1000 then
return math.floor(n / 1000) .. "K"
elseif n > 1000000 then
return math.floor(n / 1000000) .. "M"
else
return n .. ""
end
end
intvalue.Changed:Connect(scoreboardCalculations)
The code might need a little cleaning up i'm working off a crappy tablet Hope this helped

You can convert the value to string then use the length of the string to get the correct unit.
Example
local unitTable = {"K","M"} -- unit list
local function formatNumber(val)
-- count the string length take 1 to give us the base 3 count
-- math.floor is the same as v - (v % 1)
local unit = math.floor((#tostring(val) - 1) / 3)
if unitTable[unit] then
-- return a string with the correct using using ^ for devision
return tostring(math.floor( val / (1000 ^ unit))) .. unitTable[unit]
end
return tostring(val)
end
for i=0, 1000000, 100 do
print(formatNumber(i))
end
Hope this helps.
