should double have better precision or greater range?

This is extrememly machine dependant.  Usually, if you declare something
as type "int", the compiler will use the "natural" data type for the 
machine, which will usually be fastest.  The only way to tell for sure would
be to time it in various ways, on each machine you plan to use the code on.

If you don't want to go to all that work, you're probably better of just
using "int".
