   You need to define what "work properly" is supposed to mean, no kidding   
   intended, but without such an information you cannot expect reasonable   
   replies. All of these operators are defined for integer types, but they   
   might be under-specified depending on the details of your questions. A   
   machine that supports C++ must somehow emulate either of   
   twos-complement, ones-complement, or sign-magnitude representation for a   
   base two for integer types. Floating-point types can have different   
   bases than two.
