Lua:dwordToByteTable
function dwordToByteTable(Number) : Table
Converts a 32-bit dword (integer) to a table of bytes.
Function Parameters[edit]
Parameter | Type | Description |
---|---|---|
Number | Integer | The 32-bit dword to convert. |
Returns[edit]
Table — A table containing the bytes representing the dword.
Explanation[edit]
The "ToByteTable" functions convert a value (such as an integer or floating-point number) into a table of bytes that represent how the value is stored in memory.
For example, if you use wordToByteTable(1337)
:
- The decimal number 1337
is 0x0539
in hexadecimal.
- Computers typically use little-endian order, meaning the least significant byte comes first.
- So, 0x0539
is split into two bytes: 0x39
(57 in decimal) and 0x05
(5 in decimal).
- The resulting byte table is {0x39, 0x05}
or {57, 5}
.
This means:
- bytes[1] = 0x39
(the low byte)
- bytes[2] = 0x05
(the high byte)
This process applies to all "ToByteTable" functions: They break down the value into its raw bytes, ordered from least significant to most significant (little-endian).
Examples[edit]
local bytes = dwordToByteTable(0x12345678) for i, b in ipairs(bytes) do print(string.format("Byte %d: %02X", i, b)) end -- Output: Byte 1: 78, Byte 2: 56, Byte 3: 34, Byte 4: 12 (little-endian order)
