managedApproximateRealValue

This reference describes the full structure of managedApproximateRealValue. Paths include nested objects, list items and conditional branches. A branch selected by kind, contract or mode only admits its own properties.

Structure and values

Field	Options / expected values	Description
kind	"real"	Required. Selects the variant and the properties admitted in this branch.
representation	"binary64"	Required. Defines representation for this object. Observe the type, variants and bounds in the Options column.
precisionBits	53	Required. Defines precision Bits for this object. Observe the type, variants and bounds in the Options column.
minimum	number	Required. Cardinality or budget bound for the named resource. Exceeding the bound is refused; null denotes no bound only where admitted by the schema.
maximum	number	Required. Cardinality or budget bound for the named resource. Exceeding the bound is refused; null denotes no bound only where admitted by the schema.
tolerance	closed object	Required. Defines tolerance for this object. Observe the type, variants and bounds in the Options column.
tolerance.absolute	number; ≥ 0	Required. Defines absolute for this object. Observe the type, variants and bounds in the Options column.
tolerance.relative	number; ≥ 0	Required. Defines relative for this object. Observe the type, variants and bounds in the Options column.
unit	closed object OR closed object	Required. Defines unit for this object. Observe the type, variants and bounds in the Options column.
unit.[kind=dimensionless].kind	"dimensionless"	Required. Selects the variant and the properties admitted in this branch.
unit.[kind=unit].kind	"unit"	Required. Selects the variant and the properties admitted in this branch.
unit.[kind=unit].key	string; min length 1; max length 120; /^[a-z][a-z0-9-]*$/u	Required. Stable semantic identifier used by references; changing it changes identity.

Reading the contract

A path ending in [] describes each list item; {key} describes each dictionary value. The ↻ marker refers to the same recursive expression. Closed objects reject additional properties. Semantic validation denotes an additional check: matching a type does not make a reference, permission or transition valid. References must resolve in the Model and the current user context.

An older variant cannot accept properties belonging to a newer variant. The compiler checks the version and consistency of the complete Model.

Structural example

This fragment passes the schema for this section. Its business references must be defined in the enclosing Model.

{
  "kind": "real",
  "representation": "binary64",
  "precisionBits": 53,
  "minimum": 0,
  "maximum": 0,
  "tolerance": {
    "absolute": 0,
    "relative": 0
  },
  "unit": {
    "kind": "dimensionless"
  }
}
