Description
This app offers 10 very fast calculators: Solving Discrete Logarithms, Factoring Integers, Factoring and Roots of Integer Polynomials, Quadratic Equations in Integers, Modular Quadratic Equations, Sum of Four Squares, Sum of Four Cubes, Sum of Two Squares and Power, Factoring Gaussian Integers and Continued Fractions.
All calculators support 100,000 digits.
Each calculator includes help that indicates how to operate it and also a theoretical introduction to understand how it works.
The polynomial factorization and root solver calculator and the quadratic equations in integers have a step-by-step mode that shows how the solutions are found.
Most calculators have a batch mode that enables the user to find several solutions just by pressing a button. The integer factorization calculator has also a programming mode using the Blockly visual language.
The application includes two graphical applications: Ulam Spiral and Gaussian Primes.
Recent changes: Fixed buttons for operators and functions.

This is the most outstanding program for integer factorization and primality testing and just plain having fun with number theory. I have used it every day for years and highly recommend it. I would like to see the Multiplicative Order of a mod n added though there may be another way of getting this result that I am not aware of. I realize I could factor the totient to do this, but it is nice to have an all-in-one function. I would also like a Table function similar to tables in Wolfram Alpha.

We know Dario's calculators (desktop versions) for a very long time, and used them frequently for arbitrary precision calculations, factoring numbers, etc. We salute his initiative to port everything to mobile. Up to now, they work brilliantly on Android, with very few exceptions. One issue we have is the fact that the buttons became too small and are sometimes very difficult to click. We suggest that he may enlarge some of the buttons or extend the clickable area around. Good job. Kudos.
