Rolf's Scientific Calculator (http://www.squarebox.co.uk/desktop/scalc.html)
"A fully featured scientific calculator with proper operator precedence is implemented, including trig functions and logarithms, factorials, 12 levels of parentheses, logs to base 2 (a handy function for information entropists!), bitwise logical operators, hex, octal, binary and ascii display. 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!"
