 Yes, of course.
 I was confused because "?3413156131^2" did work.

 Seems not to work with 64bit machines yet...
 I think this would be quite easy to use as external library, but of
course component would be much better option.
 Right now I think I will look at bc.
 It is default command in many Linux distributions.
 Something like this; 'echo "3413156131 * 3413156131;" | bc' combined
with Gambas shell command.
