# Description

All in one calculator

---------------------

PROBLEMS? BUGS? QUESTIONS? =MAIL ME= and we will fix :)

Simple calculator: Standard functions with memory. Ability to use BigDecimal for unlimited precision.

Base-N calculator: Standard functions, logical operators (AND,OR,XOR,NAND,NOR,XNOR,NOT,SHL,SHR,ROL,ROR), decimal, hexadecimal, octal, binary and arbitrary radix, precision options (8,16,32,64,128 bits).

Scientific calculator: Standard functions including:

* Output format simple, scientific or fixed-digit floating point numbers.

* Standard complex number functions.

* Constants.

* Variable list.

* Step execution.

* Statistic calculators (including deviation, sums etc) for both real and complex numbers.

* Undo/Redo.

* Trigonometry: sin, arcsin, sinh, arcsinh, cos, arccos, cosh, arccosh, tan, arctan, tanh, arctanh for both real and complex numbers, in DEG RAD or GRA. Also Polar <-> Rectangular conversions.

* Parentheses and nesting support.

* Fraction conversions.

* Power functions (pow, sqrt, x^y, log, log10, e^x), for both real and complex numbers.

* Permutations and Combinations for big integers.

* Other functions: invert, x!, hhmmss to decimal, absolute value (or magnitute for complex numbers or determinant for matrices).

* Matrix functions: Define a matrix (any dimensions), add,subtract, multiply, determinant, transform and invert.

* Vector functions: Define a vector (any dimensions), add, subtract, internal and external product.

* Integrals: Can integrate an expression by using known integration methods and given limits.

* Sums: Calculate sum of an expression

* Solver: Solves f(x) = 0 for expression using known solver methods.

Plotter: Can plot 2D functions using AndroidPlot.

Experimental functions:

* differentiation

Unimplemented functions (yet):

* complex arcsin/arccos/arctan and sinh cosh tanh.

* Solver methods.

* limits.

* 3D plotter.

Libraries:

* Apache Common Library - http://commons.apache.org/math/

* AndroidPlot - http://androidplot.com
