Exact and Inexact Numbers
... e.g. 454 g = 1 lb or 454 g/1 lb (454 has 3 sig. fig., but 1 is exact.) 4. “Per” means out of exactly one. e.g. 45 miles per hour means 45 mi = 1 hr or 45 mi/1 hr. (45 has 2 sig. fig. but 1 is exactly one.) 5. “Percent” means out of exactly one hundred. e.g. 25.9% means 25.9 out of exactly 100 or 25. ...

Representing negative numbers
... ones' complement can be used to represent negative numbers. The ones' complement form of a negative binary number is the complement of its positive counterpart, which can be obtained by applying the NOT to the positive counterpart. Like sign-magnitude representation, ones' complement has two represe ...
