Extension: precision

FHIR Infrastructure Work Group   Maturity Level : 1 Informative Trial Use Use Context : Any
Official URL for this extension: : http://hl7.org/fhir/StructureDefinition/quantity-precision Version : 5.0.0-snapshot3
draft as of 2015-02-28 Computable Name : precision
Flags : Non-Modifier OID : TBD

Status: draft. Extension maintained by: Health Level Seven, Inc. - FHIR Core WG Context of Use : Use on Element ID decimal

Definition

Explicit precision of the number. This is the number of significant decimal places after the decimal point, irrespective of how many are actually present in the explicitly represented decimal.

Comment :

The presence of this extension does not change conformance expectations with regard to rendering and calculations that use the number - these are still based on the raw decimal value. Applications that perform calculations SHALL ensure that this extension is removed or updated to the correct precision value if the number is changed. Applications should consider using the exponential form (e.g. 2.10e3) on the raw decimal to manage significant figures, but should be mindful of human display when doing so.

Context of Use: Use on Element ID decimal
