// Num64.h -- Classes for 64-bit integers and unsigned numbers

// We define two classes here which provide arithmetic and bit shifting functions
// for 64-bit signed and unsigned numbers. We use these classes instead of the 
// LONGLONG and DWORDLONG types so this code can be ported to environments which
// don't have direct support for 64-bit data. In this implmentation we use inline
// functions as a thin layer around the 64-bit support available in the Win32 
// environment.
