I came over (Basic a bit) DOS, (Pascal a bit, Microsoft Office Basic stuff) J(ava)script, Perl to JAVA. So ever since that (it does only have signed operations) i take unsigned right shift with me. (In C and C++ i go the other way and practically work with unsigned only, except for file offsets, monetary calculations, and a bit. It approaches the Sex Pistol's singer autobiography that i never have read, "No Irish, No Blacks, No Dogs", it is just "No Floating-point, Not much Signed, No Microsoft". Or something. It comes naturally, and thus does not conflict "If it doesn't come naturally, leave it".) $ mailx -#:/ -Y 'vexpr >>> -1 1; x' 0b 01111111 11111111 11111111 11111111 11111111 11111111 11111111 11111111 0777777777777777777777 | 0x7FFFFFFFFFFFFFFF | 9223372036854775807 $ MXEXE -#:/ -Y 'echo $((-1 >>> 1));x' 9223372036854775807 --steffen | |Der Kragenbaer, The moon bear, |der holt sich munter he cheerfully and one by one |einen nach dem anderen runter wa.ks himself off |(By Robert Gernhardt)
