enum, #define, const

For storing integers with bitwise operands inside their declaration, which should I use? Performance wise I think that an enumeration works slightly faster, however what's the standard?

storing integers with bitwise operands inside their declaration
am i envisioning this correctly?

// shift in declaration
#define ONE 1>>1


if so, then i'd use a const int or typedef enum since either of those will enforce ``types-safety''.
