| web | github.com | FHIRPath Specification, published by Implementable Technology Specifications WG. This guide is not an authorized publication; it is the continuous build for version 3.0.0-ballot built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/HL7/FHIRPath/ and changes regularly. See the Directory of published versions |

The Decimal
type represents real values in the range (-10 28
+1)/10 8
to (10 28
-1)/10 8
with a step size of 10 -8
. This range is defined based on a survey of decimal-value implementations and is based on the most useful lowest common denominator. Implementations can provide support for larger decimals and higher precision, but must provide at least the range and precision defined here. In addition, implementations should use fixed-precision decimal
formats to ensure that decimal values are accurately represented.

It is the same model information file used by the Clinical Quality Framework Tooling and is included for reference as a simple formalism that meets the requirements described in the normative Reflection section above. |
