Hi,

You can simply use:

        Math.round(a);

        gremlin> a=0.123456789
        ==>0.123456789
        gremlin> Math.round(a)
        ==>0

To decide to what decimal you want, you can multiply and divide:

        gremlin> Math.round(a * 100) / 100
        ==>0.12

Note that Gremlin has full access to the Java and Groovy APIs, so:

HTH,
Marko.
