 
Comcalc (Advanced Complex Number and Logic Engineering / Scientific
Calculator)

Comcalc is an advanced powerful Complex
number and Logical Engineering / Scientific
calculator.
The interface is extremely easy to use and
supports a stack, memory and variables. 
Frequent used values or expressions can be stored in the variable list (with the variable being referenced when needed) or multiple expressions or values can be stored and retrieved from the stack. Anticipated functions are readily available.
