Description
The ultimate calculator: rotate your phone between a basic and a very capable scientific one (but you can lock it down to one, if you prefer):
In portrait mode, you have a basic calculator with: - basic mathematical operations - 00 and double-sized plus buttons - normal and financial (two decimal digits) display - percent, reciprocal, square and square root - memory add, subtract, read, write, clear - value added tax calculation - currency conversion - paper-like, scrollable multi-line display.
When you are in landscape mode, the calculator becomes a full-fledged scientific calculator with: - seven modes: normal (decimal and fraction), engineering, scientific, fixed point, complex, programmer's, statistics - true 128-bit decimal floating point calculations without rounding errors (retaining significant trailing zeroes) - precision up to 32 decimal places, number range: 1e-6143 to 1e+6144 (as per the IEEE 754 standard) - basic and advanced operations (modulo, power, root, exponential, logarithmic, trigonometric, hyperbolic) - standard mathematical operation precedence - trigonometric functions: arguments in radians, degrees and gradians, angle conversion - random numbers - infinitely nested parentheses - advanced data entry: decimals, fractions, scientific, engineering (SI) prefixes (atto to zetta) - sexagesimal calculation with degrees, minutes and seconds - rectangular and polar co-ordinates - memory functions - complex numbers, absolute values and arguments, complex support for all exponential, logarithmic, trigonometric and hyperbolic functions - programmer's mode: binary, octal, decimal, hexadecimal with logical and shift operations - statistical mode: mean values, standard and popular deviations, various x and y summa values, permutations, combinations, GCD, LCM, prime testing, factorization
