description: 'Base StructureDefinition for Quantity Type: A measured amount (or an amount that can potentially be measured). Note that measured amounts include amounts that are not precisely quantified, including amounts involving arbitrary units and floating currencies.'
derivation: specialization
name: Quantity
type: Quantity
elements:
  value: {short: Numerical value (with implicit precision), isSummary: true, index: 0}
  comparator:
    isModifier: true
    short: < | <= | >= | > - how to understand the value
    meaningWhenMissing: If there is no comparator, then there is no modification of the value
    binding: {strength: required, valueSet: 'http://hl7.org/fhir/ValueSet/quantity-comparator|4.0.1'}
    isModifierReason: This is labeled as \"Is Modifier\" because the comparator modifies the interpretation of the value significantly. If there is no comparator, then there is no modification of the value
    isSummary: true
    index: 1
  unit: {short: Unit representation, isSummary: true, index: 2}
  system: {short: System that defines coded unit form, isSummary: true, index: 3}
  code: {short: Coded form of the unit, isSummary: true, index: 4}
