    A two's compliment calculator designed for specifically for Java, but is still effective for just about any other language. It will accept two integer values and will show the binary, octal, and hexadecimal equivalence, and show how the bits interact with the logical operators not, and, or, and xor, and how primitive types are cast into other types. If there is a feature that you would like to see, let me know and I will see what I can do. I am working on a major update to how the interface works.
