# High precision calculator for very large numbers

The scientific pocket calculator handles the calculation with very large numbers and with high precision. For this enter a mathematical formula or equation into the calculator, 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 with high precision and accuracy. The input of a formula can be done by the software keys of the calculator or the PC keyboard. The following number types are available in the calculator:

The floating-point numbers have an adjustable precision from 5 to 10000 decimal digits and in the scientific notation, such as "1.5e+6", extremely large exponents of up to 4.6 quintillions are possible.

The scientific calculator makes the following arithmetic operations as mathematical functions available:

• 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
• Binomial coefficient "n choose k" with a real number "n" and a natural number "k"
• 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
