Converts a table of bytes to a 16-bit word (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 16-bit integer. If false or omitted, returns an unsigned integer. |
Returns[edit]
Number — The resulting 16-bit word (integer).
Explanation[edit]
The function takes a table of bytes (e.g., {0x39, 0x05}) and combines them into a single 16-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, byteTableToWord({0x39, 0x05}) returns 1337.
Examples[edit]
1 local word = byteTableToWord({0x39, 0x05})
2 print(word) -- Output: 1337
3
4 -- Using signed interpretation
5 local signedWord = byteTableToWord({0xFF, 0xFF}, true)
6 print(signedWord) -- Output: -1
