If I am not mistaken, everybody in this thread resorted to using a
string conversion.  Why does nobody want to calculate this
numerically?

>> x = 2011
=> 2011
>> q = 0
=> 0
>> a = x
=> 2011
>> while a>0;a,b=a.divmod 10;q+=b;end
=> nil
>> q
=> 4

Granted, this is not too short - but it works without creating a
String instance.

Kind regards

robert
