Testing for numerics

[Robert Sneidar]

The benefit would be that I could use the state of the global to  
determine if this was the first time it had been initialized and run  
some setup code. The natural state of certain globals is empty, so I  
couldn't simply test for that. If I were coding from scratch I would  
just work around this, but I am porting business logic from another  
dev environment. They use this extensively.
