Type System

Filter expressions are a very simple type system. There are only the following 13 types:

1. integer (can be abbreviated in expressions with int)

2. long

3. float

4. double

5. boolean

6. string

7. date

8. time

9. time with timezone

10. timestamp

11. timestamp with timezone

12. vertex

13. edge

Conversions are only allowed from one numeric type to another numeric type (i.e. integer, float, double, long).

Comparisons require both sides to be of the same (or convertible) type.
