About Big Integer Calculator
Calculator for big integer calculations. Arbitrarily large integers can be used, and results can be arbitrarily large. Menu options allow initial limit of 5000 digits to be increased.
For example 2^11213-1 can be calculated by first calculating 2^11213, then subtracting 1.
Modular arithmetic is supported.
The calculator uses built-in java methods and calculations are fast.
All calculations performed are stored in a list so previous answers can be seen and used in further calculations. Calculations can be copied to the clipboard, or shared directly.
Brackets and multiple operation calculations are not supported at this stage.

Wonderful app, simple interface, even does decent prime factorisation. This is a calculator specifically for massive integer calculations, those negative reviewers had no idea what is it for. Im glad that somebody did an app for this niche. Big plus for modular exponentiation. Edit: perhaps add some blank space or line in results window to separate results of consecutive calculations, now they are merged together.

YOU CANT EVEN PUT THE NEGATIVE SIGN ON..I PRESS IT A THOUSAND TIMES AND IT DOESN'T COME..BUT WHEN IT FOR ONCE ACTUALLY CAME..THIS IS WHAT I WROTE: -1 + 10..AND IT SHOWS UP 11! WTF.

I have been using this app for several years now. it is time to show my appreciation :) Only wish the buttons were bigger (taller, perhaps square instead of oval) Many thanks!

An extended version might offer gcd, kuttaka, modular sqrt.... this is a good start. I spent a lot of time on big integers, Miller Rabin primality test etc .... Can lead to career in crypto

Thanks I was hoping to find an app that can do calculations like 41^345 mod 3 and this app handled it no problem ha-ha Thanks man

Very cool, could do with a clear button but I just found out that the RCL button actually clears?

Can increase precision as needed. Will find prime factors of many numbers. Obviously really big numbers are difficult to factor, but app does try and is often successful. Remember integer division truncates

How is it even an integer calculator if u can't put a negative sign

Sorry to who ever made this. Not trying to be a hater but, when I tried to do 73 times negative 84 and it wouldnt let me. If this was made for integers, then why wont it help me with integers?????

Yeah it's sucks you don't put a minus sign in front of the number then after you do that it's mess up don't download it
