Hi. How can I simply change all bit values to opposite from a number. So that all 0''s would be 1''s and opposite. I tried using not (!) but it didn''t work because it only gives you 0 or something else (only for boolean things). Floru

Use the complementary operator ~

e.g.

x = ~x;

Use ~ in front of the variable.
