Hi

Just use [tt]expr[/tt] and it will do its best :

% set s " 33 "
 33
% set n [expr $s*2]
66

In Tcl, everything is already a string. As Feherke says, expr will deal with strings as integers; some commands deal with strings as if they were lists, etc. Now, if you want to format a string, that might otherwise be construed as, say, a floating point number, as an integer, you can always use format
