Apart from some fixes, I also added factorization of Carmichael numbers. Just enter a big Carmichael number with hundreds of digits.

Now I converted my Web factorization application to a Progressive Web Application, so you can use it as if it were a standard application in your mobile device, with an icon in the home screen and no browser interface when you open it.

I tested it on Chrome for Android. Let me know if it works with different browsers or on iOS (I do not have a smartphone with this operating system).

Seems to work on an iPhone 6S with iOS 10.3.3. Nice job.

The new feature of the factorization program is that it can show hexadecimal format while factoring. Just select the Hexadecimal output checkbox in Config menu when the program is not factoring.

You can perform several factorizations in hexadecimal by using the batch factorization mode.

To input numbers in hex, you have to precede them by the string 0x, for example 0x38 = 56.

If you see a date previous to 17 November 2017, just refresh the page.

I have started to add the "step by step" feature to my Generic two integer variable equation solver.

Only the case of discriminant b2 - 4ac positive and not square is not finished yet.

Please let me know if it is OK for you.

I've just added integer polynomial factorization to https://www.alpertron.com.ar/POLFACT.HTM . This is new code. The old Java code only supported evaluation and factorization of polynomials modulo prime powers.

Be sure that the application is dated 2 April 2019. If you see an earlier date, refresh the page.

Please let me know if you find an error.

Now the page includes the methods used for factoring polynomials.
