ElasticSearch automatically skips decimals in floating numbers

I have a panel configured to retrieve a floating number from Elasticsearh, I am interested in the decimals of that number, but apparently the panel omits the numbers after the comma and leaves them at 0 as if it were a whole number with a comma. Also Elastic’s answer comes with the omission of the numbers after the comma. in other words, it is not Grafana that omits the numbers.
Why does this happen with Elastic? Has anyone been through the same thing? and can you give me your recommendation?
