Subject [jira] [Commented] (TINKERPOP3-761) Some basic mathematical functions / steps
Date Mon, 03 Aug 2015 21:00:05 GMT

    [ https://issues.apache.org/jira/browse/TINKERPOP3-761?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14652511#comment-14652511
] 

Marko A. Rodriguez commented on TINKERPOP3-761:
-----------------------------------------------

What if "w" is your value?

Perhaps:

{code}
addOutE('a','b','weight',0.2,'c','d')
 .with('a','knows') // stupid cause you can hard code it
 .with('b',select('b'))
 .with('c',select()...)
 .with('d',select('b').outE().values('weight').mean())
{code}

Thus, we have {{with(string,traversal)}} which acts like {{withSideEffects()}}, but computed
runtime and for that particular object/step. ????

> 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.
