[jira] [Closed] (TINKERPOP-2607) Neo4j-Gremlin could not directly write and query double or float values.

["Stephen Mallette (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/TINKERPOP-2607?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Stephen Mallette closed TINKERPOP-2607.
---------------------------------------
    Resolution: Not A Bug

Gremlin Console (groovysh) assumes {{BigDecimal}} if you are not explicit with the type of number it is. 

{code}
gremlin> 0.12345.class
==>class java.math.BigDecimal
{code}

Neo4j must not coerce BigDecimal to double/float and therefore returns an error. TinkerPop does not do that coercion - it is up to Neo4j to do that sort of thing. In the Gremlin Console, or when using Groovy, I think you just need to be explicit about your types. A similar issue was raised about this with TinkerGraph where a similar answer was supplied: TINKERPOP-2603

> 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
