Cole Greer commented on TINKERPOP-3099:
---------------------------------------
Ahh yes, we currently have a real lack of type casting capability which would
become even more critical when/if we introduce some sort of native schema
capability into TinkerPop. I think [~xiazcy]'s [recent proposal for an
asNumber()
step|https://lists.apache.org/thread/bl7n4zxqopdkstrckrz0ylmx7jpk861k] is a
good way forward here.
I will close this JIRA for now as Won't Do. Feel free to reopen at any time if
you'd like to revisit it.
> 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
