Valentyn Kahamlyk commented on TINKERPOP-3099:
----------------------------------------------
I tried again at 3.7.x and it's not reproduced because bulking, basically
`inject(100b,100b,100b).sum()` works as single traversal 100 with bulk 3, so
sum is calculated as 3*100
but for local scope is other error, in console
{code:java}
gremlin> b = 100 as byte
==>100
gremlin> g.inject([b,b,b]).sum(local)
==>44{code}
> Allow sum() step to specify the result type

> 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
