This is a scientific RPN Calculator for use with Complex Numbers. It basically treats any value you enter as a Complex Number. You may perform any operation on any value.

To enter a Complex Number enter the real part of the number, press [Enter], then enter the imaginary part, followed by [i] and press [+] or [-], as you like.
To create a Complex Number from an angle, enter the angle with respect to the configured angular dimension and press [φ→]. You can scale the number just my multiplying it with the desired scale.

By pressing the Copy or Paste button, left to the mantissa, you can copy your calculated value to the clipboard or paste a value from the clipboard to the mantissa.

Clicking on the stack above the mantissa, opens a window, showing the complete stack content. You may click on any value to enter it to the mantissa or click Close, to close the window.

Performing a long click on the buttons with arrow down, e.g. sin, you can access the other trigonometric, logarithmic, root or complex functions.

The selected one will be executed immediately and replace the previous chosen on the button.

By clicking on “Conf” in the top left, you can configure the number of displayed digits, the display format, “Standard”, “Scientific” or “Engineering”, and the angular dimension, whether you use radians, rad, or degree, deg.

The calculator will always perform all calculations with full precision internally and only round to the configured precision in the display.

During stop and restart, the app persists the stack and the configuration.
