About this app
Programmer Calc is a powerful calculator designed for developers, engineers, and computer science enthusiasts. Instantly convert between hexadecimal, decimal, and binary number systems, and perform advanced bitwise operations with ease. Key Features: - Multi-base support: HEX, DEC, BIN - Real-time conversion as you type - Interactive 64-bit Bit-Set panel for granular control - Bitwise operations: AND, OR, XOR, NOT, shifts, two’s complement - Mask & Copy: Highlight and copy masked values for any data type - Paste support: Long-press to paste values into any field - Equation history tracking - Square root and modulo operations - ntuitive UI with dark/light mode - Rate and feedback options The dashboard provides a single location to input and convert values among hexadecimal, decimal, and binary representations. Long-pressing any field pastes a number directly into the corresponding system for rapid entry. The Bit-Set panel offers granular control over every bit, updating all number formats immediately after each toggle. Multiplying values that exceed 64 bits returns 1, and square roots are rounded up to the nearest integer (for example, √15 becomes 4). The Mask & Copy feature highlights the bits for the selected data type and copies the masked value to the clipboard in one step, ensuring consistent data sharing. Whether you’re debugging, reverse engineering, or learning about binary math, Programmer Calc is your essential toolkit.
What's new
Version 1.1 · Nov 10, 2026
Ready for iPhone Duo, plus two fixes. • Hex now groups in fours from the right, so 0xC0FFEE reads C0 FFEE. • The bit grid labels every row correctly: the second row now reads bits 47 to 32. • On iPhone mini and iPhone SE the keypad now fits the screen. • iPhone Duo: the full bit grid beside the keypad on the big inner screen.
