The calculation with large unsigned integer numbers is possible using the setting "uint" in the calculator. Rounding errors are impossible here because floating-point arithmetic is not used. The greatest number which the calculator can display is 2^32768 - 1. This corresponds to about 9864 decimal digits.

For the calculation with large integer numbers there are the following arithmetic operations:

- The 4 basic arithmetic operations addition, subtraction, multiplication and division
- Exponentiation
- Roots for an integer root exponent
- Logarithm calculation of an integer base
- Factorial calculation
- Greatest common divisor gcd
- Least common multiple lcm
**Modular exponentiation**x^y mod z- Multiplicative inverse

If the result of a calculation is not an integer number only the integer part of the result is calculated and displayed in the calculator.

The calculator can perform all arithmetic operations with the number bases 2, 8, 10 or 16. In order to convert a number into another number system, enter the number into the calculator and select the new number base.
