BigInt Calculator vs S

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.

Silky's Wonderful Eve Echoes Tool A companion app for Eve Echoes. This open-source app allows you to simulate fittings for your ships in the game Eve Echoes. You can set up character profiles with different skillsets and create fittings for different ships. The app will calculate attributes of all the items fitted to the ship, in the same way the game does it, eliminating the need to test the often expensive fittings in-game. You see a preview of the performance of the ship, like total damage and defense stats, and you can test around with different skills or items to see their effect on your ship.ompanion app for Eve Echoes. Features include: * Character creation and sharing * Fitting simulation and sharing Following features are supported/included in the calculations: * Ships (including captials) and some structures * Skills * Drones, normal items, group effect items * Integrated rigs * Implants (only partially) with general units * Nanocores & nanocore library * Prices of items and ships
