Thanks so much for the great discussion; although this is really a 
trivial part of what I'm doing, it's nice to be able to do it right...

In the end, I decided that:

is what I'm going to use; I really only need to make this calculation 
once, so a long function name really isn't a problem, and although I'm 
writing for NAUI tables now, I know that certain other tables use 
increments of 5 feet, so it makes sense to have a generic function 
available.

Thanks once again,

Jacob
