The scientific calculator simulates a pocket calculator and it handles the calculation with very large numbers and with high precision. The following number types are available in the calculator:

- Large integer numbers without sign
- Fraction numbers / fractions / rational numbers
- Floating-point numbers with adjustable precision and accuracy of up to 10000 decimal digits. Here extremely large exponents up to 4.6 quintillions are possible.
- Complex numbers

The scientific calculator makes the following arithmetic operations available in dependency of the number type set:

- The 4 basic arithmetic operations addition, subtraction, multiplication and division
- Exponentiation, also for fraction numbers
- Roots
- Logarithm calculation
- Trigonometric functions sine, cosine and tangent and the corresponding inverse functions
- Hyperbolic functions
- Factorial calculation
- Greatest common divisor gcd
- Least common multiple lcm
**Modular exponentiation**x^y mod z- Multiplicative inverse
- Absolute value of complex numers
- Angle of complex numers

The calculator can also be used for the calculation of mathematical formulas and equations if
the number type is set to rational numbers, floating-point numbers or complex numbers.
Simply enter a formula into the text box of the calculator using the PC keyboard, like for example

15*(6.7+sqrt(7))^3 + 7*ln(2)

After pressing the equality key on the calculator you will get the result of the formula /
equation with high precision and accuracy. You will find a description of the structure of
formulas and of the admissible mathematical functions in the help file of the scientific calculator.
