Calculation with large numbers software

Calculator for large integer numbers

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 calculator can display integer numbers with a maximum of about 20000 decimal digits.

Calculator for very large numbers, modular exponentiation

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

  1. Addition, subtraction, multiplication and division
  2. Modulo function for the calculation of the division remainder
  3. Exponentiation
  4. Root calculation for an integer root exponent
  5. Logarithm calculation of an integer base
  6. Factorial calculation
  7. Binomial coefficient "n choose k"
  8. Greatest common divisor gcd
  9. Least common multiple lcm
  10. Modular exponentiation x^y mod z
  11. 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.

Number base

The integer 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, select the output number base, enter the number to be converted into the calculator and press the equality key.
