Hello @seanccc,

Have you tried using with output string :

result = Math.PI;

Hope it helps,

Java primitive and classes are not exposed in ThingWorx Script Services.

You can create Java entities and services using the ThingWorx Extension SDK.

@smainente ,

Do you know the reason why the java primitive classes are not exposed ?   it  bring lots of convenience for development.
