Features DuoCalculator

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, programmers, 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- programmers 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, factorizationIf you have a crash, please, send a report to the support address.
This is the only way to fix it for you and for others.
