You could use the ExpressionToToken actor, in the Conversions library. You may need to set the output type of the actor, which you can do in the port configurer dialog.

Hi Hackers,
I have a basic question. How can a StringToken be converted to an IntToken or a DoubleToken? I'm assuming that it is possible with existing Ptolemy elements, but I haven't found a way. I tried using the Array and Conversions actor libraries without success, and did not see suitable functionality for this task in the Ptolemy Expression Language documentation. I may have missed something.
I am passing string messages between composite actors and would like to parse a substring of that message as a number. (e.g. For "ABC_123" I would like to convert "123" as a number I can do math with.)
Thanks in advance for any pointers you can share.
Kevin
