function byteTableToWord(Table, [Signed]) : Number
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]
local word = byteTableToWord({0x39, 0x05}) print(word) -- Output: 1337 -- Using signed interpretation local signedWord = byteTableToWord({0xFF, 0xFF}, true) print(signedWord) -- Output: -1
