About Big Integer Calculator

Calculate with BIG integers! Find 2^4423 - 1, and HUGE factorials such as 1234!

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.
