> Improve Redis INCRBYFLOAT output accuracy for very large values
> ---------------------------------------------------------------
>
> Key: GEODE-8897
> URL: https://issues.apache.org/jira/browse/GEODE-8897
> Project: Geode
> Issue Type: Test
> Components: redis
> Reporter: Jens Deppe
> Assignee: Jens Deppe
> Priority: Major
> Labels: pull-request-available
>
> Currently native redis appears to be able to apply INCRBYFLOAT on values that
> are below the max of unsigned long long (18446744073709551615). However,
> since we're treating numbers as \{{double}}s we can lose precision for very
> large values. For example:
>
> {{set val 18446744073709551614
> incrbyfloat val 1}}
> incorrectly returns {{18446744073709552000}}
> Native redis produces a correct result.
