CONNECTED CRANES FOR ENHANCED CONNECTED JOBSITE SMIE, the pioneer in crane anti-collision systems since 1975, has always looked for innovation to help crane operators and Jobsites to work with maximum safety and productivity. Thanks to the new 4G connectivity combined with the existing Wi-Fi mesh network, SMIE offers a unique architecture which support new features available on your mobile and tablet. THE MOST INNOVATIVE ANTI-COLLISION AND ADVANCE ZONING SYSTEM ProSITE unique architecture allows the Jobsites managers to have transparency and visibility on the Jobsite operations. They can now instantly connect to the system from anywhere and access all information, generate reports in real time and simultaneously on all the jobsite cranes. Number of lifting cycles, total operating time, downtime, weather data … Most most relevant information is here! Furthermore, they can also remotely interact with the anti-collision systems, manage work areas for machines and share planning of crane activity. Thanks to the updated connection technologies, all operators can have an overall vision on Jobsites activities and perfectly manage the anti-collision system anywhere. Website: https://smie.com

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.
