Complex Number Calculator Precision 45 1.0.0.1

Button Mod stands for modulus and works on the same way as abs button. Button mod stands for modulo. Button Log stands for principal value of complex Log and is duplicated by button ln. Button log(z) works as Log(z)/ln(10) for complex z and as decimal logarithm for real z, although in Complex Analysis log denotes multi-valued function log(z)=Log(z)+2πni.

Complex Number Calculator Precision 45 calculates all standard functions of complex variable: trigonometric, hyperbolic, inverse. In addition the calculator calculates some complex special functions: Gamma function, Lower Incomplete Gamma function, Upper Incomplete Gamma function, Lower Regularized Gamma function, Upper Regularized Gamma function, Sinc function, Normalized sinc function, Beta function, Incomplete Beta function, Regularized Incomplete Beta function, Sine Integral function, Lower Sine Integral function.

This 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)].

Major Features:

1. In the default mixed mode the calculator treats numbers as integers wherever it is possible.
2. There are 10 variables (or constants) available for storing frequently used numbers.
3. All calculation results are reflected in History rich-text-box, which can be saved in file or printed.
4. Unlimited number of user constants can be entered and maintained by user.
5. Fundamental constants are available in the prebuilt Common Constants list.
