/**
* The reason that we list evaluate methods with all numeric types is for both
* better performance and type checking (so we know int + int is still an int
* instead of a double); otherwise a single method that takes (Number a, Number
* b) and use a.doubleValue() == b.doubleValue() is enough.
*
* The case of int + double will be handled by implicit type casting using
* UDFRegistry.implicitConvertable method.
