Github user JPercivall commented on the issue:

@pvillard31 I addressed your comment and added to the unit test to verify
that it properly handles the exceptions. A couple notes:
1: The exception handling is not pretty. That said, I don't think there is
a better/more concise way to do it since we're dealing with configurable
reflection calls.
2: Normally I would have the exception testing in individual tests with an
"@Test(expected = AttributeExpressionLanguageException.class)" but since this
is a large test class (that probably should be broken up) that tests all the EL
and I wanted to keep it concise.

> 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.
