    simon@alibi ~ % ruby -e 'puts ( (-1) ** 0.5)'
    NaN
  • FrewSchmidt2 [9844] % perl -le 'print (-1) ** (1/2)'

    • indeed you are:

      C:\Users\burak>perl -MO=Deparse -le "print (-1) ** (1/2)"
      BEGIN { $/ = "\n"; $\ = "\n"; }
      print(-1) ** 0.5;
      -e syntax OK

      try this instead:

      print( (-1) ** (1/2) )

      • Hah! The funny thing is that I was talking to someone about this bug YESTERDAY. Thanks.
