in reply to #perl.br calc - A Perl Shell

Perl, computing... hmm ;-) Compare these: 
$ echo 'x=y=1.2; x+=1.1; x-=1.1; x; y; x==y' |bc |xargs echo
1.2 1.2 1

[download]
$ perl -wle '$x=$y=1.2; $x+=1.1; $x-=1.1; $,=$"; print $x, $y, $x == $
+y'
1.2 1.2

don't you love perl? ;-)

    As a quick calculator (especially with vector/matrix ops) I like the J programming language. It's not quite good as a real programming language IMO, but it's ideal for doing some quick numeric computations. GNU octave is good for the same purpose as well.
