Hello @seanccc,

 

Have you tried using with output string :

 

var pi = Math.PI;

result = Math.PI;

 

 

 

Hope it helps,

@Ciprian-Traian ,

 

Thank, you .  var pi = Math.PI;  works,  but I got the same error when doing further testing :

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.
