inheritable relation |
The class of Relations whose properties can be inherited downward in the class hierarchy via the subrelation Predicate.

single valued relation |
A Relation is a SingleValuedRelation just in case an assignment of values to every argument position except the last one determines at most one assignment for the last argument position. Note that not all SingleValuedRelations are TotalValuedRelations.

| Children |
binary function | The Class of Functions that require two arguments. |
| | continuous function | Functions which are continuous. This concept is taken as primitive until representations for limits are devised. |
| | quaternary function | The Class of Functions that require exactly four arguments. |
| | ternary function | The Class of Functions that require exactly three arguments. |
| | unary function | The Class of Functions that require a single argument. |
| Instances | assignment | If F is a Function with a value for the objects denoted by N1,..., NK, then (AssignmentFn F N1 ... NK) is the value of applying F to the objects denoted by N1,..., NK. Otherwise, the value is undefined. |
| | greatest common divisor | (GreatestCommonDivisorFn ?NUMBER1 ?NUMBER2 ... ?NUMBER) returns the greatest common divisor of ?NUMBER1 through ?NUMBER. |
| | Latitude | LatitudeFn is a VariableArityRelation used to denote a parallel of latitude. Examples: (LatitudeFn North (MeasureFn 38.0 AngularDegree)), (LatitudeFn South (MeasureFn 23.0 AngularDegree) (MeasureFn 30.0 ArcMinute)), (LatitudeFn South (MeasureFn 60.0 AngularDegree) (MeasureFn 0.0 ArcMinute) (MeasureFn 0.0 ArcSecond)), (LatitudeFn North (MeasureFn 42.0 AngularDegree) (MeasureFn 7.89 ArcMinute)). |
| | least common multiple | (LeastCommonMultipleFn ?NUMBER1 ?NUMBER2 ... ?NUMBER) returns the least common multiple of ?NUMBER1 through ?NUMBER. |
| | list | A Function that takes any number of arguments and returns the List containing those arguments in exactly the same order. |
| | Longitude | (LongitudeFn ?DIRECTION @ROW) denotes a meridian of longitude. Note that LongitudeFn is a VariableArityRelation. Examples: (LongitudeFn East (MeasureFn 180.0 AngularDegree)), (LongitudeFn West (MeasureFn 122.0 AngularDegree) (MeasureFn 24.0 ArcMinute)), (LongitudeFn East (MeasureFn 121.0 AngularDegree) (MeasureFn 0.0 ArcMinute) (MeasureFn 15.0 ArcSecond)), (LongitudeFn West (MeasureFn 80.0 AngularDegree) (MeasureFn 6.78 ArcMinute)). |
