Changing Text Formatting

As the title says I want to change some text, I have 2 codes but they do not match as things are going on.

I would like tyo use the Frist Code for everything.

First Code (This code is being used for my Nameplates):
Code:
local FormatValue = function(number)
	if number < 1e3 then
		return floor(number)
	elseif number >= 1e12 then
		return string.format("%.3fT", number/1e12)
	elseif number >= 1e9 then
		return string.format("%.3fB", number/1e9)
	elseif number >= 1e6 then
		return string.format("%.2fM", number/1e6)
	elseif number >= 1e3 then
		return string.format("%.1fK", number/1e3)
	end
end
Second Code (This code is being used for my UnitFrames):
Code:
		local shorts = {
			{ 1e10, 1e9, "%.0fB" }, --  10b+ as  12B
			{  1e9, 1e9, "%.1fB" }, --   1b+ as 8.3B
			{  1e7, 1e6, "%.0fM" }, --  10m+ as  14M
			{  1e6, 1e6, "%.1fM" }, --   1m+ as 7.4M
			{  1e5, 1e3, "%.0fK" }, -- 100k+ as 840K
			{  1e3, 1e3, "%.1fK" }, --   1k+ as 2.5K
			{    0,   1,    "%d" }, -- < 1k  as  974
		}
		for i = 1, #shorts do
			shorts[i][4] = shorts[i][3] .. " (%.0f%%)"
		end

		hooksecurefunc("TextStatusBar_UpdateTextStringWithValues", function(statusBar, textString, value, valueMin, valueMax)
			if value == 0 then
				return textString:SetText("")
			end

			local style = GetCVar("statusTextDisplay")
			if style == "PERCENT" then
				return textString:SetFormattedText("%.0f%%", value / valueMax * 100)
			end
			for i = 1, #shorts do
				local t = shorts[i]
				if value >= t[1] then
					if style == "BOTH" then
						return textString:SetFormattedText(t[4], value / t[2], value / valueMax * 100)
					else
						if value < valueMax then
							for j = 1, #shorts do
								local v = shorts[j]
								if valueMax >= v[1] then
									return textString:SetFormattedText(t[3] .. " / " .. v[3], value / t[2], valueMax / v[2])
								end
							end
						end
						return textString:SetFormattedText(t[3], value / t[2])
					end
				end
			end
		end)
Hopefully someone can help me with the code.

Thanks
Coke

Here's what I've started doing with my number displays.
Lua Code:
  1. local math_abs=math.abs;
  2. local math_floor=math.floor;
  3. local math_log10=math.log10;
  4. local math_max=math.max;
  5. local tostring=tostring;
  6.  
  7. local NumberCaps={"K","M","B","T"};
  8. local function AbbreviateNumber(val)
  9.     local exp=math_max(0,math_floor(math_log10(math_abs(val))));
  10.     if exp<3 then return tostring(math_floor(val)); end
  11.  
  12.     local factor=math_floor(exp/3);
  13.     local precision=math_max(0,2-exp%3);
  14.     return ((val<0 and "-" or "").."%0."..precision.."f%s"):format(val/1000^factor,NumberCaps[factor] or "e"..(factor*3));
  15. end

It dynamically adjusts the precision based on if the number is in the 1's, 10's, or 100's. It'll revert to scientific notation if the abbreviation accessed is out of the defined scope. You can add more in the NumberCaps table.
