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
> Neo4j-Gremlin could not directly write and query double or float values.

> 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

> 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();

> h3. Reproduce
> {code:java}
> gremlin> g.addV().property('vp2', 3.49203472E8)
> [349203472:java.math.BigDecimal] is not a supported property value
