Programmer Calculator: Hex4.1.1

Hex, decimal, octal and binary — all four bases on one screen, updating as you type. Programmer Calculator is a base converter and bitwise calculator for developers, engineers and computer science students.

CALCULATE IN ANY BASE
• Enter an expression in hex, decimal, octal or binary and read the result in all four at once
• Arithmetic with +, −, ×, ÷, parentheses and operator precedence
• Bitwise operators: AND, OR, XOR, NOT, shift left and shift right
• Switch the input base at any time without retyping the expression

MATCH YOUR INTEGER TYPE
• Word size: 8, 16, 32, 64 bits or unlimited
• Signed or unsigned representation
• Results respect the word size and representation you choose, so what you read matches what your code does

SEE EVERY STEP
• Open the steps view on any calculation
• Every operation and every intermediate value, in the order they are applied
• Useful for debugging a result that came out wrong, and for learning how precedence and bitwise operators behave

HISTORY
• Every calculation you confirm is saved
• Tap an entry to bring it back into the calculator
• Your history stays on your device

BUILT FOR THE JOB
• Light and dark themes, following your system setting
• Phone and tablet layouts, in portrait and landscape
• Long-press a result to copy it to the clipboard
• The calculator works offline

WHO IT IS FOR
• Developers working in C, C++, Java, Kotlin, Rust, Go, Python and assembly
• Embedded and hardware engineers working with registers, masks and flags
• Students learning number systems, two's complement and bitwise logic
• Anyone who needs a hex converter, binary converter or base converter that also does real arithmetic
