Are you saying that int and double do not match?  They are both 
arithmetic types, and the number of significant digits supported by a 
double (about 17) is more than enough to represent all 32-bit integers.

We need it to force the division to be done in floating point (as opposed 
to two integers).  But there are other ways of doing that, some of which 
I mentioned in this thread several days ago.
