Logic:

Logic operators perform boolean operations on values on the boolean stack, popping them off the stack in the process and pushing the result onto the stack, either true or false. The result obviously will depend upong the operator was used and the boolean values on the stack at the time.

Since version: 2.4 you can set an Energy cotst per bitwise command instance. default is 0.
