@ -20,8 +20,18 @@ Typically `0` is used to indicate an unsigned (positive) integer and `1` to
indicate a signed (negative) number. The rest of the bits are the magnitude (the
actual numerical value).
We can demonstrate with an 8-bit binary system.
We can demonstrate with an 8-bit binary system, encoding `5`: `0000 0101`. Here
the furthest bit (aka. the "most significant bit" (MSB)) at the $2^8$ position
is `0`, designating that the number is unsigned. The signed equivalent is
`1000 0101`, with the MSB being `1` designating the number as signed. When we
are working with signed numbers, the MSB is known as the **signed bit**.
