The picture in this page is useless without specifying the "weight" of each bit!
Lately I've started seeing another usage of MSB == "Main Stream Blogosphere".
See for instance

It's possible to mathematically calculate the greater of two numbers using the MSB without having to use code branching:
If Y is greater than X then Y-X will have an MSB of 0 If X is greater than Y then Y-X will have an MSB of 1
Therefore (Y x NOT(MSB(Y-X)))+ (X x MSB(Y-X)) will return the larger number.
Proof: 3 - 2 = 1, MSB(3-2) = 0, NOT(MSB(3-2)) = 1, therefore (3 x NOT(MSB(3-2))) + (2 x MSB(3-2)) = 3 x 1 + 2 x 0 = 3
Have fun with that!! —Preceding unsigned comment added by 213.120.253.12 ( talk) 16:12, 5 August 2009 (UTC)
The binary example image at the right states: "The msb in an 8-bit binary number represents a value of 128 decimal." Should this read "The msb in an 8-bit unsigned binary number..."? I know the word unsigned is mentioned earlier, but it would make sense to use it here as well (to me). -- Iaindb ( talk) 05:49, 12 August 2009 (UTC)
Might be worthwhile noting the historic use of MSB in storing negative numers digitally, now replaced by Two's Complement. Another bit would be added to a number (on the left, effectively a new MSB) and would be used to indicate polarity; 0 for positive, 1 for negative. — Preceding unsigned comment added by A - J - Hadley ( talk • contribs) 23:01, 12 September 2012 (UTC)
