      Uncertainty in Measurement: There are 2 types of numbers, exact and inexact. Exact numbers. are counts and they are defined. Inexact numbers. are derived from measurements and contain some degree of uncertainty or error. Precision and Accuracy. Precision. is how well measured quantities agree with each other. How repeatable was the data. Accuracy

      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 …

For example if a message had 3 order groups and each order group had 3 OBX, the Sequence number of the last OBX in the message would be 9.

      The SI units are mass in kilograms, length in meters, and volume in the derived units of m3. The assumed uncertainty in a number is (1 in the last significant figure of the number. The precision of an instrument is related to the number of significant figures associated with an experimental reading on that instrument.

      All of these are examples of exact numbers. By contrast, an inexact number is a number that is measured, usually by using some sort of measuring tool such as a ruler, tape measure, scale, or measuring cup. Measured numbers are always inexact to some degree.
