Review Comment:
confused by this type declaration of `DT` and the use of 199. is this meant
for `N`? and isn't the next number 205, not 199? and curious why serialization
tests would be passing under this configuration....
> Add number conversion step asNumber()
> -------------------------------------

> 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].
