Exact and non exact numbers
Essentials of General, Organic, and Biological Chemistry
Exact numbers: numbers we use in counting and defining other quantities are assumed to be exact and to have an infinite number of significant figures.The number “1” is exact as well and could be expressed as 1.0000000000000 Inexact numbers: approximate numbers, numbers obtained from measurements. Again, the “1” can be considered exact. Usually when one is going across units, the ...
Conceiving exact numbers without exact number words

Exact and inexact numbers. In scientific work, we come across two kinds of numbers: exact numbers and inexact numbers. An . exact. number. is one which has no uncertainty associated with it. For example, when we say that there are 1000 g in a kilogram, the number ‘1000’ is an exact number – it cannot be 1001 or 999 but is exactly 1000.

None of the rules below apply to exact numbers or to design numbers. All exact numbers and design numbers are considered to have more significant digits than any other numbers in the problem, so the precision of the computed value does not depend on the number or digits or decimal places shown in an exact number or a design number.
