A full-fledged scientific calculator with very high precision. Calculate with up to 32 decimal digits or unlimited integer precision in its many modes.\r\n\r\nThe normal scientific mode supports true 128-bit decimal floating point calculations without rounding errors (retaining significant trailing zeroes), with precision up to 32 decimal places, in the range of 1e-6143 to 1e+6144 (as per the IEEE 754 standard).\r\n\r\nIt supports all basic and advanced operations like modulo, power, root, exponential, logarithmic, trigonometric, hyperbolic with standard mathematical operation precedence and infinitely nested parentheses.\r\n\r\nTrigonometric functions accept their arguments in radians, degrees and gradians, with direct angle conversion between these.\r\n\r\nCalculations are possible with usual decimals, fractions (proper and mixed), sexagesimal (degree-minute-second), scientific-engineering SI units (atto to zetta).\r\n\r\nFull support for complex numbers: absolute values, arguments, Euler's form; all exponential, logarithmic, trigonometric and hyperbolic functions are fully functional for complex numbers.\r\n\r\nProgrammer's mode with infinite precision of binary, octal, decimal and hexagesimal numbers and all usual bitwise operations.\r\n\r\nStatistical mode with mean values, standard and popular deviations, various x and y summa values, permutations, combinations, GCD, LCM, primality test and integer factorization.
