------------------------------------

             Summary: Neo4j-Gremlin could not directly write and query double or float values.
                 Key: TINKERPOP-2607
                 URL: https://issues.apache.org/jira/browse/TINKERPOP-2607
             Project: TinkerPop
          Issue Type: Bug
          Components: neo4j
    Affects Versions: 3.4.10
         Environment: TinkerPop Version : 3.4.10
Neo4j Version : 3.5.27
OS : CentOS8
Storage Backend: in-memory

            Reporter: Liwei Liu


h2. Neo4j-Gremlin could not directly write and query double or float values.
h4. Environment

TinkerPop Version : 3.4.10

Neo4j Version : 3.5.27 

OS : CentOS8

Storage Backend: in-memory 

Data size: 100 vertices, 200 edges
h4. Bug description

 Neo4j-Gremlin could not directly write and query double or float values. We need to specify the detailed type of the property value. However, we can do this in TinkerGraph or from Java API.
h4. Current behavior
{code:java}
java.util.concurrent.ExecutionException: org.apache.tinkerpop.gremlin.driver.exception.ResponseException: [349203472:java.math.BigDecimal] is not a supported property valuejava.util.concurrent.ExecutionException: org.apache.tinkerpop.gremlin.driver.exception.ResponseException: [349203472:java.math.BigDecimal] is not a supported property value at java.util.concurrent.CompletableFuture.reportGet(CompletableFuture.java:357) at java.util.concurrent.CompletableFuture.get(CompletableFuture.java:1908)
{code}
h3. Expected behavior

 When enter the same code in TinkerGraph.
{code:java}
gremlin> g.addV().property('vp2', 3.49203472E8)
==>v[3192]{code}
 When try to do it through Java API from Neo4j, it is legal.
{code:java}
Vertex v1 = g.addV().property("author",3.49203472E8).next();
{code}
When detailed type declared, it is legal.
{code:java}
gremlin> g.addV().property('vp2', 3.49203472E8d)
==>v[19946]
{code}
h3. Reproduce
{code:java}
gremlin> g.addV().property('vp2', 3.49203472E8)
[349203472:java.math.BigDecimal] is not a supported property value
{code}
