> h1. TinkerGraph sometimes could not query float values.
> h3. Environment
> Version: 3.4.10
> OS : CentOS8
> Storage Backend: in-memory 
> h3. Bug description
> TinkerGraph sometimes could not query float values.  To be detailed, when create a new TinkerGraph database in memory. We could insert a float value but not query it.
> h3. Current behavior
> {quote}gremlin > g.addV().property('vp2',0.65780294)
> ==>v[1011]
> gremlin > g.V().has('vp2',0.65780294){quote}
> The second query returns with nothing. However, after several times or query it with 0.65780294f, it would return v[1011]. It means that TinkerGraph sometimes could not query float values which is abnormal.
> h3. Expected behavior
> When enter the same code in neo4j-gremlin or janusgraph, it would return normal result like:
> {quote}gremlin > g.V().has('vp2',0.65780294)
> ==>v[3192]{quote}
> h3. Reproduce
> {quote}        GraphTraversalSource g = connection.getG();
>         g.E().drop().iterate();
>         g.V().drop().iterate();
>         try {
>             String tuery = "g.addV().property('vp2',0.65780294)";
>             connection.getClient().submit(tuery);
>             String query = "g.V().has('vp2',0.65780294) ";
>             System.out.println("query: " + query);
>             try{
>                 List<Result> results;
>                 results = connection.getClient().submit(query).all().get();
>                 for (Result r : results) {
>                     System.out.println(r);
>                 }
>                 }
> }{quote}
> Or
> {quote}gremlin > g.addV().property('vp2',0.65780294)
> gremlin > g.V().has('vp2',0.65780294) {quote}
