I am dividing two doc\_counts from an aggregate to produce a percentage and compare it to a percentage. Does integer division in painless produce a float or another integer? I'm using the ctx.vars to get it into a log message to try to debug. Does the log message go to the elastic log or somewhere else?

"inline": "if ((ctx.payload.current\_poll.aggregations.fandp.buckets.0.doc\_count \> 0) && (ctx.payload.current\_poll.aggregations.fandp.buckets.1.doc\_count \> 0)) { ctx.vars.xx = (ctx.payload.current\_poll.aggregations.fandp.buckets.1.doc\_count / (ctx.payload.current\_poll.aggregations.fandp.buckets.0.doc\_count + ctx.payload.current\_poll.aggregations.fandp.buckets.1.doc\_count)); return ctx.vars.xxx \> ctx.payload.week\_poll.aggregations.avg\_fail; } else { return false; }"

Found that painless does do int division (1/3 = 0). I'm not sure of the 'proper' way to convert but I used the python trick (1\*1.0)/3 and I'm getting a decimal number.

this is indeed the correct 'trick'. Painless copies its division logic from java, where dividing two integers will result in an integer.
