[jira] [Commented] (NIFI-2791) Create a new Expression Language Function to support Java.lang.Math operations

["Joseph Percivall (JIRA)" <ji...@apache.org>]

Joseph Percivall commented on NIFI-2791:
----------------------------------------

With the pruning going on for 1.1.0 I'd like this to keep it's fix version. I have done much of the work for it already but it is blocked by NIFI-1662. So just need NIFI-1662 to be reviewed/merged (fix version of 1.1.0) and then I will rebase, finalize and open a PR. 

These go hand in hand and having this Math functionality will go a long way to facilitate numeric operations using EL.

> Once EL is improved to support decimals (NIFI-1662) it will be desired to support higher level math functions than are currently implemented. The easiest way to do this is to provide access to the Math class[1]. This should provide all the building blocks necessary to do any desired operations on decimals.
