>                 Key: TINKERPOP-3166
>                 URL: https://issues.apache.org/jira/browse/TINKERPOP-3166
>             Project: TinkerPop
>          Issue Type: Improvement
>          Components: language
>    Affects Versions: 3.8.0
>            Reporter: Yang Xia
>            Priority: Major

> Given the addition of the {{asString()}} and {{asDate()}} steps in the 3.7 
> line, it should also be helpful to add an {{asNumber()}} step that does 
> numerical casting/conversions.
> The current idea is for the {{asNumber()}} step to convert the incoming 
> traverser to the nearest parsable type (e.g. int or double) if no argument is 
> provided, or to the desired numerical type, based on a number token 
> ({{{}N{}}}) provided. Like the {{asDate()}} step, it will not be scoped (for 
> now, scopes can be added in the future).
> Some conjured examples:
> {code:java}
> gremlin> g.inject(5).asNumber()
> ==> 5    // parses to int
> gremlin> g.inject(5.123f).asNumber()
> ==> 5.123 
> gremlin> g.inject(5.43).asNumber(N.int) 
> ==> 5 {code}
> More details can be found in the [proposal 
> doc|https://github.com/apache/tinkerpop/blob/master/docs/src/dev/future/proposal-asnumber-step-6.asciidoc].
