I know my problem is very easy, even for begginer but:

Qt Code: 
  1. int aa=2;
  2. int bb=3;
  3. double abd=aa^bb;
To copy to clipboard, switch view to plain text mode 
but i have to do it like this but i couldn't
Qt Code: 
  1. double aa=2.09;
  2. double bb=3.04;
  3. double abd=aa^bb;
To copy to clipboard, switch view to plain text mode 
error: invalid operands of types `double' and `double' to binary `operator^'
What is the solition?
