Complex Number Calculator Precision 45 1.0.0.0

Complex Number Calculator Precision 45 1.0.0.0 is a program designed for Windows 7, Windows Vista, Windows XP, Windows Server 2008, Windows Server 2003, and Windows 2000. It is perfect tool for scientists, engineers, professors, and graduate students.

This software is a complex number calculator and works with complex numbers, but also can be used as a real number calculator, that is a scientific calculator. The calculator has backward compatibility with College Scientific Calculator series, Scientific Calculator Precision 54, Scientific Calculator Precision 63, Scientific Calculator Precision 72, Scientific Calculator Precision 81, Scientific Calculator Precision 90, Complex Calculator Precision 18, Complex Calculator Precision 27, and Complex Calculator Precision 36.

Any formula which works in College Scientific Calculator will work in this calculator. For that some buttons are duplicated. 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.

Major Features:

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