[Jprogramming] J as a calculator

[Raul Miller]

Yes.

And each has their own contexts where they are more convenient.

-. is nice with @ & &. &.: &: @:

1 - is nice when building verb trains.

And there's easily an hour's worth of teaching material here (or
significantly more, for advanced classes), related to the history of
computing, logic, boolean algebra, probability, and so on...

   require'plot'
   N=:0.01*i.101
   X=: ["0/~ N
   Y=: ]"0/~ N
   Z=: *&.-./~ N
   $X
101 101
   $Y
101 101
   $Z
101 101
   plot (,X);(,Y);(,Z)

Thanks,
