Scientific Calculator Precision 90 1.0.0.0

Scientific Calculator Precision 90 1.0.0.0 is an useful application for scientists, engineers, professors, and students to perform complex mathematical calculations. Scientific Calculator Precision 90 is programmed in C#. All calculations are done in proprietary data type.

The calculator handles mathematical formulas of any length and complexity. Calculation history can be stored into text file or printed. There are ten variables or constants available for storing often used numbers. Prebuilt Common Costants list with fundamental constants. Unlimited User Constants list. Precision of calculations is 90 digits. Trigonometric, hyperbolic, inverse and combinatorial functions. Special numbers NaN, Uncertainty, and Infinity.

The calculator follows classical approach when uncertainty of f(x) calculation is estimated by formula max|(derivative(f))|*|x*uncertainty(x)|, where maximum of function derivative is considered on interval [x-uncertainty(x),|x+uncertainty(x)], and uncertainty(x)=|x|*10^(-precision). Gamma function, Lower Incomplete Gamma function, Upper Incomplete Gamma function, Beta function, Incomplete Beta Function, Sine integral function. Summation and product operator have four levels of nesting.
