JMX Exporter converting real numbers into 64 bit floats

[Rip Jal]

Checking on JMX exporter localhost end point,I see that metrics ( like java_lang_Memory_HeapMemoryUsage_committed  )get converted into double values with E notation so 613941248 gets converted into 6.13941248E8.

We are using JMX exporter to publish values on the endpoint and then doing some internal monitoring on top of that.  

Is it possible to export such values in real format ?

No, the Prometheus exposition format supports only floats, so there is no way to force the client libraries to integers. If you are parsing it independently, you will need to accept floating point values.
