# Calculator for fraction numbers, rational numbers

The calculation with fractions or rational numbers is possible using the setting "rat" in the calculator. The input of fractions is done by numerator, fraction line "/" and denominator. There are up to 10000 decimal digits available for numerator and denominator, respectively.

For the calculation with fraction numbers there are following arithmetic operations:

• The 4 basic arithmetic operations addition, subtraction, multiplication and division
• Exponentiation
• Roots
• Cancelling down of fractions by entering a fraction number and pressing the equality key on the fraction calculator
• Logarithm calculation
• Trigonometric functions sine, cosine and tangent and the corresponding inverse functions
• Hyperbolic functions
• Conversion between fraction number, floating-point number and mixed notation of a fraction number
• Factorial calculation
• Binomial coefficient "n choose k" with a rational number "n" and a natural number "k"

If the result of a calculation cannot be represented as a fraction number because either the result is not rational or an overflow in the fraction number in numerator or denominator arises, the fraction calculator switches to the number type "real" and displays an approximated value.
