Joseph Percivall commented on NIFI-1662:
----------------------------------------
As a note: this will need to take into account the PriorityAttributePrioritizer
as well.

> Improve Expression Language to Enable Working with Decimals

> Key: NIFI-1662
> URL: https://issues.apache.org/jira/browse/NIFI-1662
> Project: Apache NiFi
> Issue Type: Improvement
> Reporter: Joseph Percivall
> Assignee: Joseph Percivall
>
> Currently the math operations in Expression Language use Longs to evaluate
> numbers. This leads to any decimal places getting truncated when performing
> operations like divide.
> EL should be improved to enable the user to evaluate math expressions using
> doubles.
> Another desired portion of this would be to open up the static Math class [1]
> methods (using reflection) to further enable working with Decimals.
