zCalc: Calculator with Complex Number Support

This program provides an easy-to-use, yet powerful numeric calculator for calculations with real or complex numbers. It let's you enter the computation "by hand" instead of by pressing buttons, including any level of parenthesis. In addition, you can store results of your computation in "variables" which you can use for further computations.

Note: The latest version of this program can handle real and complex numbers z = x + i y and plots complex numbers in the complex plane so you can visualize addition, multiplication, etc. of complex numbers graphically.

-10 * (2.4 - Pi) [ENTER]
angle = 45 [ENTER]
sin(radians(angle))^2 + cos(radians(angle))^2 [ENTER]
z1 = 3 + 5i [ENTER]
z2 = 4 - 3i [ENTER]
w = z1 * z2 [ENTER]
