> Key: ASTERIXDB-2293
> URL: https://issues.apache.org/jira/browse/ASTERIXDB-2293
> Project: Apache AsterixDB
> Issue Type: Bug
> Components: FUN - Functions
> Reporter: James Fang
> Priority: Minor
>
> I receive incorrect results when dividing. The following queries give the incorrect result in AsterixDB and Couchbase, but gives the correct result in Postgres.
> For example:
> 1) array_avg( [1.2,2.3,3.4] );
> 2.3000000000000003
> 2) array_sum( [1.2,2.3,3.4] ) / 3;
> 2.3000000000000003
> 3) 6.9 / 3;
> 2.3000000000000003
>
> Using the [1.1,2.2,3.3] for 1 and 2, and 6.6 instead of 6.9 in for number 3 gives,
> 2.1999999999999997
