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.

Please note this is a calculator for big number nerds.  It is not a handy calculator for working out percents or solving quadratics, and it doesn't have trigonometric functions.  This calculator is mainly for extremely large numbers which may or may not have intriguing characteristics, such as being fake square roots of 1 to a certain modulus.  Fake square roots of 1 are hard to check on a normal calculator, and that's where this calculator has the edge.

Prime factors of an integer can be calculated.  For example, 2^67 - 1 can be found by finding 2^67, then subtracting 1.  Pressing the prime factor button will then search for factors of this number (in the case of this number, "Cole's number", the Pollards Rho depth will have to be increased using the menu, but the app can find the two factors).

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.
