Logical Model: REAL - Detailed Descriptions

Active as of 2024-12-18

Definitions for the REAL logical model.

Guidance on how to interpret the contents of this table can be found here

0. REAL
Definition

Fractional numbers. Typically used whenever quantities are measured, estimated, or computed from other real numbers. The typical representation is decimal, where the number of significant decimal digits is known as the precision. Real numbers are needed beyond integers whenever quantities of the real world are measured, estimated, or computed from other real numbers. The term "Real number" in this specification is used to mean that fractional values are covered without necessarily implying the full set of the mathematical real numbers.
