Bitwise operations


and       w1 w2 -- w        core       ``and''


or       w1 w2 -- w        core       ``or''


xor       w1 w2 -- w        core       ``x-or''


invert       w1 -- w2        core       ``invert''


lshift       u1 n -- u2        core       ``l-shift''


rshift       u1 n -- u2        core       ``r-shift''
Logical shift right by n bits. 
2*       n1 -- n2        core       ``two-star''
Shift left by 1; also works on unsigned numbers 
d2*       d1 -- d2        double       ``d-two-star''
Shift left by 1; also works on unsigned numbers 
2/       n1 -- n2        core       ``two-slash''
Arithmetic shift right by 1. For signed numbers this is a floored division by 2 (note that / not necessarily floors). 
d2/       d1 -- d2        double       ``d-two-slash''
Arithmetic shift right by 1. For signed numbers this is a floored division by 2.
