Here are methods I've used during the years: - perldl in a shell - ipython in a shell - type in an arithmetic expression into google - Use (/ 199.0 2.0)[control u][control x][control e] in emacs - command line with "perl -e 'print 199/2,"\n"' - created several (because I forgot where I put the old one) readline print eval loops for perl - Used easycalc on my palm pilot - Written a script in /tmp that I continously edit and run
But I have never got around to using programs that look like a calculator in a window on the screen.
