  calctool  -  README.

  This is V1.2 of a simple desktop calculator, which can be a Sun Tool
and also works poorly on a normal ascii terminal in non-suntool mode.
Mimimal changes should be needed to port this to other BSD and Sys V
machines.  Please let me know what changes if any you have to make to
get it working on your machine.

  It has a lot more features then the last version. These include:

(1) You can GET and PUT the calculator display.
(2) Every calculator button has an equivalent key press.
(3) Built in help, press HLP followed by another selection.
(4) Normal arithmetic + - x / with constants.
(6) Logical operations AND OR XOR XNOR and NOT.
(7) Results can be displayed (and calculated) in binary, octal,
    decimal and hexidecimal.
(8) The result can be shifted multiple places to the left and right.
(9) Fractional precision can be 0 to 9 places.
(10) There are ten memory registers for storing and retrieving numbers.
(11) A backspace key to remove last character of the display. Note
     that this loses internal numeric accuracy as the number is
     recalculated from the display value.

  This is a list of the calculator buttons with their equivalent keys:

    Q      Quit                           N      Logical XNOR.

  Thanks to Ed Falk at Sun Microsystems (Mountain View) for some of the
basic algorithms used.

  Suggestions for furthur improvement would be most welcome, plus bugs,
comments and flames to me.
