Then you would know that 1/2 = 0, and that wouldn't trouble you. In Lisp, 1/2 is what you would might expect. For example (= (+ 1/2 1/2) 1) returns t. And Maxima also knows about 1/2. In Sage, 1/2 is the fraction 1/2 and so you do have : sage: 1/2 1/2 sage: 1/2+1/2 1 On the

I waited a little bit before saying my bit. You are making my work as a person packaging sage for a distro difficult. Heck it was difficult when you started shipping pari 2.4 snapshots while you were release manager. The only thing that keeps me from quitting is pure dumb stubbornness. As for my

If I recall correctly sometimes one needs to use dash instead of bash on Cygwin, but nonetheless it somehow works, maybe because dash is only necessary when going outside of Sage for rebasing or something? To be precise, /bin/bash is a genuine bash on Debian, /bin/sh points to /bin/dash
