public abstract class SumLikeSPARQLAggregationFunctionSymbolImpl
extends UnaryNumericSPARQLAggregationFunctionSymbolImpl

TODO: find a better name For aggregates like SUM where AGG(xsd:integer) returns an xsd:integer. Therefore the aggregation of integers must be done separately from the aggregation of floating numbers.
