Warning, here positive means >=0, not >0. It should be clearer in description, definition depend on country! --- It is a tutorial task, moved. === Edit(Francky)--> I saw that modification of description is done. Fine. Usually, one can thanks for pointing 'errors', but rather not simply hide the comment. :-( === RE: Sorry & Thanks Francky. Actually I didn't hide your comment feeling bored or something else. I just did this thinking nothing. :) Last edit: 2014-03-12 09:40:58 |
