Programmers Calculator

Programmer Calculator is a focused tool for developers, students, and anyone working with binary and hexadecimal numbers. Convert between number bases, perform integer calculations, and inspect individual bits—all on your device. Four bases, one clear view See hexadecimal (HEX), decimal (DEC), octal (OCT), and binary (BIN) values together with live conversions. Built for bitwise work Calculate with AND, OR, XOR, NOT, and left and right shifts. Use the interactive bit display to toggle individual bits and explore how each change affects your number. Control your integer format Choose 8-, 16-, 32-, or 64-bit word sizes and switch between signed and unsigned values. Fixed-width arithmetic wraps to the selected word size, with two’s-complement interpretation in signed mode. Precise integer calculations Perform addition, subtraction, multiplication, division, and modulo using exact integer arithmetic rather than floating-point approximations. A comfortable everyday tool Use hardware-keyboard input, choose a light or dark theme, and keep your preferred number base, word size, signedness, and theme between sessions. All calculations and conversions run locally on your device.
