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.

I downloaded this calculator mainly for the Arbitrary Precision capability, but quickly discovered that this only works in the 4-function basic mode, and not in the Scientific Mode, where all of the trig functions, etc. are located. It's a very nice, quite powerful calculator, but unfortunately it's output in Scientific mode is limited to the standard 15 or 16 significant digits. If the author adds "Big Number" arbitrary precision capability to the Scientific mode, I'll re-install and give it another try. Would also appreciate an RPN mode, to make the I/O more user friendly for people who use Hewlett-Packard RPN calculators. The function plotting and graphing feature looks interesting, but I couldn't get it to plot anything but a flat horizontal line, and the "Help" file is just a few basic tips to get you started. I checked the author's website to see if there are Docs for this app, and the website doesn't even show that this app exists.

Ok OK but keyboard hard to read. Small type and silly colors=poor contrast

Incomplete functions please add the secondary trigonometric functions secant, cosecant and cotangent. please add it so integration and differentiation will be easier. and please create an offline version.
