Daniel Kuppitz commented on TINKERPOP3-750:
-------------------------------------------
IIRC that was done because we want to be able to do {{.count().is(0)}} instead
of {{count().is(0L)}}. Same for things like {{.outE("rated").has("stars",
between(3.5, 5))}} - that would also work if {{stars}} is of type {{Integer}}.
> Compare should not have special case for Number

> The current implementation of {{Compare}} has a special case for {{Number}}
> which uses {{doubleValue}} for all comparisons. However, this fails for some
> implementations of {{Number}}, e.g. {{BigInteger}}. Also, most
> implementations of {{Number}} implement {{Comparable}} for appropriately
> typed arguments. It should be more robust and less surprising to simply use
> {{Object.equals}} and {{Comparable.compareTo}}. This would also be more
> performant as it removes the {{instanceof}} checks.
> If we want the option of treating all numbers as doubles, perhaps something
> called {{CompareDouble}} would be more appropriate.
