Surprisingly, it seems to work properly in Windows PowerShell (version 3).
PS C:\> 1.0 / 6.0 0.166666666666667 PS C:\> 1/6 0.166666666666667 Also seems to work in Python 3 as sepp2k mentioned. The other two languages I have readily available on REPL, Scala and Ruby, both do integer division and yield 0.
