Logical Model: REAL: RealNumber (V3 Data Type)

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.

Usage:

• Use this Logical Model Profile: Criterion (CDA Class), Observation (CDA Class) and ObservationRange (CDA Class)
