==== Explanation ====
=== Variable Initialization: ===
  local name_of_element = nil --- they're a string
  local text_element = nil
  local uiid = nil
  local trigger_variable = nil --- they're a string

...

=== Getting the variable from variable library: ===

	local result, new_coins_result = VarLib2:getPlayerVarByName(e.eventobjid, 3, trigger_variable )

    * **VarLib2:getPlayerVarByName** is used to retrieve a player's variable from variable library.

    * See more here: **[[developer_center:developer_editor:script:varlib|Varlib]]**

===Convert it into a new string following the International System of Units (SI) ===
<code LUA>
if new_coins_result >= 1000 and new_coins_result < 1000000 then 
    new_re = string.format("%.1f", new_coins_result / 1000) .. "K"
elseif new_coins_result >= 1000000 and new_coins_result < 1000000000 then 
    new_re = string.format("%.0f", new_coins_result / 1000000) .. "M"
elseif new_coins_result >= 1000000000 and new_coins_result < 1000000000000 then
    new_re = string.format("%.0f", new_coins_result / 1000000000) .. "B"
elseif new_coins_result >= 1000000000000 and new_coins_result < 1000000000000000 then
    new_re = string.format("%.0f", new_coins_result / 1000000000000) .. "T"
else 
    new_re = tostring(new_coins_result)
end
</code>

  * This section formats the new_coins_result value based on its magnitude. Depending on the range in which **new_coins_result** falls, it formats the number with appropriate suffixes like "K" (thousands), "M" (millions), "B" (billions), "T" (trillions), etc.

===Updating UI ===
<code LUA>
Customui:setText(e.eventobjid, uiid, text_element, name_of_element .. new_re)
</code>
**Customui:setText** updates the text in the UI, combining **name_of_element** with the formatted **new_re**.

===Event Registration: ===
<code LUA>
ScriptSupportEvent:registerEvent("UI.Show", round)
</code>
The **round** function is registered as a handler for the "UI.Show" (you can use "Game.AnyPlayer.EnterGame) event, meaning it will be called whenever the "UI.Show" event is triggered.
