Scientific Calculator Precision 81

If you're looking for a handy, fast, and reliable tool for performing complex mathematical calculations, look no further than Scientific Calculator Precision 81. This powerful software program is written in C# and uses a proprietary data type to ensure precise calculations of mathematical formulas of any length and complexity.

Not only can you store your calculation history in a text file or print it out, but Scientific Calculator Precision 81 also comes with ten variables or constants for frequently used numbers. Plus, there's a prebuilt list of common constants containing fundamental constants and an unlimited user-generated constants list.

With a precision of 81 digits, this calculator supports trigonometric, hyperbolic, inverse, and combinatorial functions, as well as special numbers such as NaN, Uncertainty, and Infinity. When estimating the uncertainty of f(x) calculations, the calculator follows the classical approach by using the formula max|(derivative(f))|*|x*uncertainty(x)|, where the maximum of the function derivative is considered on the interval [x-uncertainty(x),|x+uncertainty(x)], and uncertainty(x)=|x|*10^(-precision).

Other advanced features include the Gamma function, the Lower Incomplete Gamma function, the Upper Incomplete Gamma function, and the ability to nest summation and product operators up to three levels. Overall, Scientific Calculator Precision 81 is a must-have tool for anyone performing complex mathematical calculations.
