Type Inference

See also: Data Transfer / Primitive Management for how Adhoc handles primitive types at runtime.

Ints and Longs

ints are generally treated as longs.

• Aggregations (e.g. SUM) will automatically turns int into long
• EqualsMatcher, InMatcher and ComparingMatcher will automatically turns int into long

Floats and Doubles

floats are generally treated as doubles.

• SUM will automatically turns float into double
• EqualsMatcher, InMatcher and ComparingMatcher will automatically turns float into double

Numbers

• Aggregations should generally aggregates as long, else double.
