NerdCalc

NerdCalc is a binary, hexadecimal and decimal calculator that displays all three number bases at the same time. With NerdCalc, you can quickly switch which base you are inputting and the result of your calculations is always updated for all three bases, no matter what the current input mode. NerdCalc supports both unsigned and 2’s complement, to allow for negative numbers, and can perform basic arithmetic and logic operations as well as bitwise shifting. Enjoy!
