hello friends would like to ask for help with a function. I want to convert 4bytes example to the value 100 for hex code = 64 but I did not find the function for that.

I found the one that makes hex for string which is this below.
I would like the function similar to 4bytes to hex.
I appreciate the answers.

Code:
function string.fromhex(str)
    return (str:gsub('..', function (cc)
        return string.char(tonumber(cc, 16))
    end))
end


words='6F6CC3A1207465737465'
reve=string.fromhex(words)
print(reve)





I would like to transform 4bytes 100 >> Hex 0064

Thank you very much, my friend. =)

Sorry, one more question and if I want to make the format stays 100 = 64 00 with the spaces. Thank you.

Code:
local number = 100
local bytes = dwordToByteTable(number)
local result = string.format("%02X %02X %02X %02X", unpack(bytes))
print(result)
