Wow. I always thought "least significant bit" meant, in the common big-endian bit notation, the last bit - with emphasis on the bit
word, i.e. either 1 or 0.
Have I got a real mess in my head (probably not, I just googled for definitions and the onse I checked are consistent with what I
wrote, http://www.google.com/search?hl=en&lr=&q=%22least+significant+bit%22) or is the meaning of the phrase poorly defined?
