You betcha!

The Arg struct has a char * for name and a caddr_t for value.  When a
float is loaded into a caddr_t, your friendly C compiler converts the
float into an int.  Ain't that great?!

Now perhaps you can understand why there are no examples of widgets
which use float resources.  :-(

You can set up your resource as a pointer to a float, but that brings
its own problems.

Good Luck!
