Converts a table of bytes to a 32-bit dword (integer).
Function Parameters[edit]
| Parameter | Type | Description |
|---|---|---|
| Table | Table | A table containing the bytes to convert (least significant byte first). |
| Signed | Boolean (optional) | If true, returns a signed 32-bit integer. If false or omitted, returns an unsigned integer. |
Returns[edit]
Number — The resulting 32-bit dword (integer).
Explanation[edit]
The function takes a table of bytes (e.g., {0x78, 0x56, 0x34, 0x12}) and combines them into a single 32-bit value.
The first element is the least significant byte (little-endian order).
If Signed is true, the result is interpreted as a signed integer.
For example, byteTableToDword({0x78, 0x56, 0x34, 0x12}) returns 0x12345678 (305419896 in decimal).
Examples[edit]
1 local dword = byteTableToDword({0x78, 0x56, 0x34, 0x12})
2 print(dword) -- Output: 305419896
3
4 -- Using signed interpretation
5 local signedDword = byteTableToDword({0xFF, 0xFF, 0xFF, 0xFF}, true)
6 print(signedDword) -- Output: -1
