Andrea C commented on TINKERPOP-3099:
-------------------------------------
Some things to consider:
* whatever fix we do for sum should be made consistent with other related
steps such as math
** check for recent changes in master that were made to handle similar issue
with other steps
* needs to be done in 4.0 if we decide to auto convert the type (instead of
adding a parameter to specify the output type) if overflow will happen as that
would be a breaking change
> Allow sum() step to specify the result type

> Key: TINKERPOP-3099
> URL: https://issues.apache.org/jira/browse/TINKERPOP-3099
> Project: TinkerPop
> Issue Type: Improvement
> Components: process
> Affects Versions: 3.6.7, 3.7.2
> Reporter: Valentyn Kahamlyk
> Priority: Major
>
> in some cases `sum()` step do not allow to get the correct result due to
> overflow.
> For example `g.inject(100b,100b,100b).sum()` will lead to
> `ArithmeticException`.
> Good to have a way to get the result using a different type for summation,
> for example by providing seed, `g.inject(100b,100b,100b).sum(0L)` can produce
> 300L
