Big Integer Calculator: 100 digits

x is not prime

The calculator takes two integers x and y as input, and produces integer results.
This means that even when you divide x by y, you always get an integer; the fractional part of the result is truncated. For example, the operation 14/5 will produce the integer 2, rather than the decimal 2.8. (To calculate the remainder of division, use the mod button.)

Simplest arithmetic operations support million-digit input values – and even larger if the user doesn’t mind the long wait. Primality tests (based on the Miller-Rabin algorithm) become noticeably slower when x is over a hundred digits long. Powers xy may be slow to compute for input values x containing tens of digits and 3-digit exponents y. Factorials x! become slow for input values x ≈ 10000.
