Numeric tags lose precision when using ElasticSearch

[kevinearls]

I created a tag using ".withTag("floatTag", Math.PI)". When using Cassandra or the all-in-one it returns "3.141592653589793" (which is what (Number) Math.PI returns) but with ElasticSearch I only get "3.141592654"

I have tried to reproduce with Jaeger 1.12 and ES 5.6.10 and I got 3.141592653589793.

The span was reported using java client.

      tracer.buildSpan("foo")
          .withTag("string", "00001")
          .withTag("integer", 1)
          .withTag("float", 1.001)
          .withTag("string1", "1")
          .withTag("float1", new Double(1))
          .withTag("PI", PI)

I am closing this is it is not an issue anymore, feel free to re-open is similar issues happen.
