I added a bunch of formatting - way more than the numbers can hold I think.

But in control.lua line 27 - function format_money()

I changed it to be:
"
function format_money(n)
if n == nil then return "0u" end

local suffixes = {
    [93] = "Tg",
    [90] = "NVg",
    [87] = "OVg",
    [84] = "SpVg",
    [81] = "SxVg",
    [78] = "QiVg",
    [75] = "QaVg",
    [72] = "TVg",
    [69] = "DVg",
    [66] = "UVg",
    [63] = "Vg",
    [60] = "NmDc",
    [57] = "OcDc",
    [54] = "SpDc",
    [51] = "SxDc",
    [48] = "QiDc",
    [45] = "QaDc",
    [42] = "TDc",
    [39] = "DDc",
    [36] = "UDc",
    [33] = "Dc",
    [30] = "No",
    [27] = "Oc",
    [24] = "Sp",
    [21] = "Sx",
    [18] = "Qi",
    [15] = "Qa",
    [12] = "T",
    [9] = "B",
    [6] = "M",
    [3] = "K",
    [0] = ""
}

local abs_n = math.abs(n)
local suffix = ""
local factor = 1

for exp = 93, 0, -3 do
    if abs_n >= 10^exp then
        suffix = suffixes[exp] .. "u"
        factor = 10^exp
        break
    end
end

local formatted_number = string.format("%.3f", n / factor)

if n < 0 then
    formatted_number = formatted_number
end

return formatted_number .. suffix

end
"

This is great! Could you submit this as a PR

There, I should have created the PR on github

Merged and released!
