The second number (0.2) is not the amount to be incremented each time, it's the next number in the sequence. Since, 0.2 differs from 0.1 by 0.1, each additional number in the sequence will be incremented by 0.1. > Something's gone dreadfully wrong. > sage: [0.2,0.2,..,0.9] > OverflowError: cannot convert float infinity to integer There's no difference between 0.2 and 0.2, so it will never make it to 0.9. > Now I'm just confused. > sage: [0.2,0.1,..,0.9] > [] Going down from 0.2 to 0.1 and so on, you'll never reach 0.9. --Mike -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
