  calculator (package math/calculator-1.1)

    Tcl/Tk version 7.4/4.0
    calculator release 1.1

 -----------------------------------------------------------------------------

calculator is a full-featured Tcl/Tk calculator with the following keys:

  OFF  HELP const pi   AC  
  DRG  MENU put   e    CE  
  HYP  sin  cos   tan  sqrt
  ARC  x!   10^x  exp  x^2 
  M+   1/x  log   ln   y^x 
  M-   EE   (     )    /   
  STO  7    8     9    *   
  RCL  4    5     6    -   
  XCH  1    2     3    +   
  CLR  0    .     +/-  =   

Each key has a keyboard binding, so that users can interact with the 
calculator via the keyboard alone.  In addition, pasting a selection on the
display activates the appropriate key sequences, so that externally-selected
numbers or expressions may be pasted in.  Backspacing (keyboard only) 
is also supported.

The "help" key displays all of the keyboard bindings.

The "const" key brings up a listbox dialog with the several fundamental
constants (planck constant, speed of light, for example).  The "put" key
appends the current result at the end of the constants list, so that
the next time the dialog is displayed, the saved result can be retrieved.

The "menu" key posts a menu of several additional options: a mortgage
payment calculator, a compound-interest calculator, toggle logging of
calculator activity, display the current calculator stack, and set the
precision.

The "DRG" key controls "degrees", "radians", or "grads" modes.
