Matt Frantz commented on TINKERPOP3-761:
----------------------------------------
I'm not sure what the different {{mult}} overloads do. Would the two-arg
{{mult}} ignore the traverser and multiply two values? Or is it a reducing
barrier step, and if so, what is the second arg for?
For the add edge steps, what if all parameters are labels, and you use {{by}}
to generalize?
{noformat}
...addOutE('knows', 'b', 'weight', 'w')
.by() // b
.by('weight') // w
...addOutE('a', 'knows', 'b', 'weight', 'w')
.by() // a
.by() // b
.by('weight') // w

> Project: TinkerPop 3
> Issue Type: Improvement
> Components: process
> Affects Versions: 3.0.0-incubating
> Reporter: Daniel Kuppitz
> Assignee: Marko A. Rodriguez
>
> Every once in a while I wish to have steps for some basic mathematical
> operations ({{add()}}, {{sub()}}, {{mul()}}, {{div()}}). Since {{sub(num)}}
> is the same as {{add(-num)}} and {{div(num)}} is the same as {{mul(1/num)}},
> we would only need two new step implementations.
> Oh, and then there's also {{mod()}}, thus 3 new step implementations.
