Have you experienced yourself trying really hard to convert from hexadecimal to binary, or other common base for programming purpose? You won't experience that issue again after mastering Programmer Calculator.

Change View - Programmer Calculator

As its name, this calculator is designed for programmers with many logical operations and functions embedded, such as AND, OR, XOR, etc. To open the Programmer Calculator, you need to open your calculator and then go to Apple ▸ View ▸ Programmer (keystrokes: Command-3.

Number Representation

Every engineers should know that binary representation is the most important things as machine can only detect either 1 or 0. With Programmer Calculator, converting decimal number, which is our common number representation, into binary, hexadecimal, or even octal representation is a piece of cake.

Six buttons right below the calculator's display are used for that purpose, i.e. changing number representation.

Logical Operators

Logical operators are also included, i.e. AND (which will result in 1 if both operands are 1), OR (which will result in 0 if both operands are zero), NOR (which will result in 1 if both operands are 0) and also XOR (that will result in 0 if both operands are the same).

And many other functions for you to manipulate the binaries.
