The better way to go is to call

   C:\Octave\Octave-5.1.0.0\mingw64\bin\octave.bat

which setups some necessary paths in cmd.exe and PowerShell and define
some alias for it.  Then you can pass commands to Octave by adding for
example:

   --eval "format long; sin (pi/2) + 4"

and get the output to the respective MS Windows shell.  But some small
experiments showed that PowerShell does not properly pass the --eval
input to Octave and causes errors, which I have no clue how to
fix/properly escape them at the moment.

   --eval "sin(pi)"

If you have a satisfying solution accepting arbitrary input, please
share it with us =)
