What is the difference between a Numeric Input, Numeric Output and Numeric Public within a script program.
Is using a Numeric Public a less efficient choice (as opposed to using a Numeric Input or Numeric Output) that will generate negative overhead in the AS?

Want to determine best practices when choosing numeric types during script programming.
- Numeric Input is a read only numeric (from the point of view of the script program) that accepts a binding.
- Numeric Output is a write only numeric (from the point of view of the script program) that accepts a binding.
- Numeric Public is both read and write (from the point of view of the script program). Numeric Public also accepts a binding.
(A Numeric Public can be bound to both a Graphic and a Value Object to allow overriding of values from a Graphic. See SBO Script Public.zip for an example)
When choosing the numeric type in a script program there is no overhead cost difference between using one of these numeric types vs the others.

NOTE b3 and Infinet Controller scripts do not support "Numeric Public", but "Numeric Output", in these controller scripts, can be used in a similar way to "Numeric Public" The Bound value is read by the script as well as being written to.
