### Problem Type (问题类型)
lack info (文档描述缺失)
### Your Question (问题描述)
## Problem Type
`lack info` in `apache/hugegraph-doc`. If submitted through the public
fallback
form in `apache/hugegraph`, select `configs (documentation related)`.
## Your Question
### Environment
- Server Version: Apache HugeGraph 1.7.0
- Gremlin Version: 3.5.1
- Backend: memory
- Data Size: 2 vertices and 1 edge
### Missing documentation information
The documentation defines numeric property types and supported `has`
predicates but does not state how Gremlin-Groovy numeric literal classes are
compared with a stored `DOUBLE` property. An unsuffixed decimal literal is
not
necessarily a Java `Double`, so this affects query results.
### Reproduction case
```groovy
schema.propertyKey('weight').asDouble().ifNotExist().create()
schema.vertexLabel('DocVertex').useCustomizeStringId().ifNotExist().create()
schema.edgeLabel('DocEdge').sourceLabel('DocVertex').targetLabel('DocVertex').properties('weight').ifNotExist().create()
g.addV('DocVertex').property(T.id, 'a').iterate()
g.addV('DocVertex').property(T.id, 'b').iterate()
g.V('a').addE('DocEdge').to(__.V('b')).property('weight', 1.0d).iterate()
g.E().has('weight', P.within(1.0)).has('weight', P.lt(1.5)).count()
```
### Expected result
Please document whether numeric predicates use value-based numeric coercion
or
require compatible runtime numeric classes, including any required literal
suffixes.
### Actual result
The traversal returns `0` even though the edge stores the `DOUBLE` value
`1.0`,
which is numerically within `1.0` and less than `1.5`.
