Number - Significant (Figures|Digits|Bits)

Data System Architecture


A significant digit is a digit that can't be removed from the number without modifying its value.



The most significant digit is the left-most nonzero digit


The least significant digit is the right-most known digit.


The total number of significant digit is the total number of digit
