The following two statements seem to contradict themselves (it is late here and I am studying, so I will revisit this in the morning again, but I think we have an error in description for LEAST/MOST:
It 'A byte is made up of 8 bits' {
<#
Each bit can be set to either 0 or and each has a value based
on its position.
The most significant bit, the largest value, is first. The least
significant bit, the smallest value, is last.
Bit position Value
------------ -----
1 128
2 64
3 32
4 16
5 8
6 4
7 2
8 1
This order is known as Big Endian.

As the signing bit is always the least significant, converting the 8 bit
binary value above to a larger type, such as, Int32 will create a positive value.

I think this should read As the signing bit is always the most significant...
