Scientific calculator

This application turns your phone into a scientific calculator.

The app uses rational numbers instead of floating point numbers. It allows operations which give a rational number, as for instance the four basics operations (+, -, x, /), to give a result with no truncation at all.

For functions such as logarithms and trigonometrics, the precision can be set from 12 to 20 digits after the floating point. Adjust it according to the computation power of your device and your patience!

In addition to basic operations, it allows to perform the following functions :

Decimal and Neperian logarithms and their reverse functions,
Trigonometric functions, either “normal” or hyperbolic.
Angle conversions from and to degrees, radians and grades.
Statistic functions : mean, variance, standard deviation,
Addition and substraction of times, in the hh:mm:ss format,
Probability : combination and arrangement,
Conversions from and to the decimal base, the binary base and the hexadecimal base.

All these functions are available on real numbers and on complex numbers as well (to the extent that these functions are defined on complex numbers).

It is fitted with an infinite number of memory registers (to the extend permitted by the device's memory) allowing results to be stored for later use.
