How do I abbreviate numbers?

Hello! I wonder how i abbreviate numbers in leaderstats and text gui's. My leaderstats is already created so dont include one in a script. The 2 leaderstats Value are Speed and Money. Pls i rlly need help.

so if you want it displayed you want to put these in text labels put this in a localscript in the screen ui, not in the frame. (not tested)

local player = game.Players.LocalPlayer
local leaderstats = player.leaderstats

--assuming this script is in a screengui with the texts displayed in it
script.Parent.Frame.SpeedLabel.Text = "Speed: "..leaderstats.Speed.Value
script.Parent.Frame.MoneyLabel.Text = "Money: "..leaderstats.Money.Value
