Rounding off values to CEIL in JSON Inline

Elastic Stack Kibana
1

I have an integer field in a metric and in its JSON Inline I have a calculated field (stop_time-start_time) and the value of a calculated field is a float value. But somehow I am getting only an integer part of that value and not float. Also an integer is always a floor value. (The output is always an integer may be because the field used for metric is of type integer).

ex:

1.4 = 1
1.9 = 1
0.7 = 0

How can I change it to float or if not then atleat make it CEIL. because I dont want to show the field value as 0 (zero).

Can you check the mappings for that field? If elasticsearch thinks it's an integer that could be why it's dropping the decimal
