Programmer Calculator vs Bit Alchemist

Programmer calculator is a tool to support developers to convert numbers between different radix, to calculate CRC of strings or hex bytes. More features is under development and will be delivered in future.

Bit Alchemist is a fast, native programmer's calculator built for people who think in hexadecimal, binary, and bits — developers, embedded engineers, reverse engineers, and CS students. Switch instantly between hex, decimal, octal, and binary. Choose 8-, 16-, 32-, or 64-bit word sizes with signed or unsigned interpretation, and watch every base update live as you type. Enter full C-style expressions with parentheses and correct operator precedence, or work in immediate/chain mode — one engine, one result.
