What do the most significant and least significant digits represent?
Stephen Davies, Ph.D. Version 2.2.2 Through Discrete Mathematics A Cool Brisk Walk / Chapter 1
"By the way, we will often use the term least significant digit to refer to the right-most digit (2, in the above example), and most significant digit to refer to the left-most (5). “Significant” simply refers to how much that digit is “worth” in the overall magnitude of the number. Obviously 239 is less than 932, so we say that the hundreds place is more significant than the other digits."
