Bases vs BigInt Calculator

Easily convert between Binary, Decimal and Hexadecimal values and display associated character or emoji. Bases is an easy to use, base converter. Type in hexadecimal, decimal or binary values (8 bit or 16 bit) and see the value converted and the unicode character equivalent along with the unicode descriptor text. The application can displays; - Decimal - Hexadecimal - Binary - Associated Character (if any) - Unicode Descriptions Note: This application was primarily designed for the iPhone but can also be used on an iPad. It actually works great on iPad Pro, if you share the the iPad screen with my HexToASCII application. Features: - 8 bit and 16 bit modes. - Unicode descriptions of various character and control code. - Increment or decrement values at the touch of a button. - Right shift or left bits. - If a value has an associated character it will be displayed. - Supports sharing Initially developed to assist me to explain both hexadecimal and binary arithmetic to my students. I thought it would be good to share. Enjoy!

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.
