Subject: Want to make sign_mag and long sign_mag class, can I?
Summary: long modifies a class?

I want to build a class to do signed-magnitude arithmetic.  (Yes I know I could do
this with int and long int.)  I want to make a class called sign_mag that would be
a 16 bit sign-magnitude number.  Then I also want another class that would be a 
32 bit sign-magnitude number.  I would like to be able to specify this like:

sign_mag  A16BitSM;
long sign_mag A32BitSM;

I cannot figure out if this is even possible much less how to do it.

I also want to override -, +, *, /, to work with both classes and get the proper
type casting.  (sign_mag is converted to long sign_mag before being added to a
long sign_mag)

Any help or pointers in the right direction will be appreciated!

Toodles
Andy
