There are actually two separate calculators with different keypad layouts, a scientific calculator and one for logical operations. To switch from scientific to logical mode press the 'HEX' but note that pressing 'DEC' once just changes the displayed value to decimal. You have to press the 'DEC' key a second time to return to scientific mode!"
