BinHexDec vs BigInt Calculator

BinHexDec is a smart and effective programmer's calculator. It features conversion between Binary, Octal, Decimal and Hexadecimal, standard bitwise operations AND, OR and XOR, and immediate operations including bitwise shifts, rotates, increment and decrement, and also includes one's and two's complement operations. BinHexDec features a smart entry system, allowing you to change number base and bit size, and conduct immediate operations whilst entering operands. The calculator responds smartly and intuitively. The delete key is also smart - removing the last character from the current operand, not just the last character entered. On the iPad a scrolling history displays your previous calculations. All results are automatically sent to the clipboard enabling you to paste them straight into other applications. In addition you can send any operand you're entering to the clipboard by just tapping the main display. The developer welcomes your comments and suggestions to improve this application. Please get in touch with you ideas and suggestions.

A calculator for those who need more than standard precision. Integers of any size stay exact — no overflow, no lost digits. Fractions and square roots are shown to 10, 50, 100 or 1000 decimal places, as you choose. Multiplying numbers thousands of digits long takes milliseconds, and independent parts of an expression are computed in parallel on all CPU cores. Features - Addition, subtraction, multiplication, division - Powers and square roots (0.5, 1.5, 2.5…) - Parentheses and correct operator precedence - mod with fast modular powers: 3^(2^127-2) mod (2^127-1) takes an instant - Factorial (!) and the functions gcd, lcm, binom, isprime and nextprime - Hexadecimal and binary: integer results in hex, numbers like 0xff and 0b101 - Scientific notation (6.022e23) and superscript powers (2¹²⁷) - Three independent tabs M1, M2, M3 for parallel work - Keyboard bar with ( ) − √ ! on iPhone and iPad - Your tabs are saved between launches; Undo after clearing - History of recent calculations - A result screen with as many digits as fit, the digit count and the order of magnitude; ≈ marks results that are not exact - Every digit of a huge result in numbered rows, with a jump to any digit - Live progress and elapsed time for long calculations, with a Cancel button - Copy the result with one tap and the expression from the menu; share a result as text, a file or an image card - VoiceOver support; on Mac, menu commands and keyboard shortcuts - Built-in help with examples - Alternative symbol support: × ÷ : and a comma as decimal separator How it works Type a power with ^: 2^127-1. An exponent of 0.5 is a square root: 2^0.5. Parentheses work as in mathematics: (2+3)*4. mod has the lowest precedence: 2^255-19 mod 8. Function arguments are separated by a semicolon: gcd(12; 18). On iPhone, functions and 0x numbers are typed on a hardware keyboard or pasted. Who it's for - Students and math teachers - Developers working with cryptography and large primes - Number theory researchers - Anyone hitting the limits of ordinary calculators No ads, no trackers, no accounts. Works on smartphone, tablet, and computer.
