CalcEn

CalcEn is a simple scientific calculator for real and complex number arithmetic

A few of the special features that are unique to CalcEn include the following:

- All familiar functions (sin, cos, ln, etc) can accept real and complex arguments.

- The inverse trigonometic functions can accept arguments outside the range [-1, 1].

- ln and log functions can accept arguments less than zero.

- Complex numbers can be written in rectangular or polar form.

- Complex results can be converted between polar and rectangular forms.

- The number of significant digits used to display the result of a computation can be modified in the settings menu (the default value is 4).
