Wrong, 1 is not equal to .99999... 1/9 aprox. equal to .11111... 1 = .9999... + .0000....1 !ihlpb!bryan Bryan DeLaney BTL Naperville, IL

#R:ihlpb:-26600:whuxlb:7200013:000:372 whuxlb!ech Jan 26 02:11:00 1983 Hold on, thar... .111..., carried to infinity, IS 1/9, and .999..., carried to infinity, IS 1. There is no roundoff error in infinite decimal expansions. Even in the computer world, the equality sometimes holds: for example, in APL, a "fuzz" is applied to output results (although not for intermediate ones). If you type in enough 9's, it will echo "1". =Ned Horvath=
