Byte Transformations
These transformations only apply to the least significant byte, regardless of the endianness.
| Name | Operation |
|---|---|
| Add | byte + 128 |
| Subtract | 128 - byte |
| Negate | -byte |
Byte Order
Also known as Endianness.
| Name | Order |
|---|---|
| Big | 4, 3, 2, 1 |
| Little | 1, 2, 3, 4 |
| Middle-Big* | 3, 4, 1, 2 |
| Middle-Little* | 2, 1, 4, 3 |
*Middle-Big and Middle-Little are not a standard order or naming scheme. I call them that because they start with the big significant bytes or the little significant bytes.
