heXcalc(1)               X Version 11(1 October 1989)                heXcalc(1)


NAME
      heXcalc - programmers calculator for X

SYNOPSIS
      heXcalc [standard X options]

DESCRIPTION
      heXcalc is a mutli-radix calculator that offers the standard C integer
      operations.

OPTIONS
      The standard X toolkit options.

OPERATION
      Calculator Modes:  The calculator operates in several modes. The modes
      are controlled by buttons on the calculator. The current mode setting is
      indicated by setting the corresponding button to "insensitive".


      Pointer Usage:  All operations are done with the Button1 (usually
      leftmost button on the pointer).  These can be changed using the
      translation manager.


      button Usage:  Most of the buttons are self explanatory (for C
      programmers).  The others are explained below.


      16/32 buttons:  These buttons toggle the calculator between 16 and 32 bit
      mode.

      sgn/usgn buttons:  These buttons determine whether data is treated as
      signed (2's complement) or unsinged.


      CE/C button:  Clears the current entry without affecting other settings
      of the calculator.


      C button:  Clears everything. The display and memory are set to zero.
      The mode is set to signed, 32 bit decimal.


KEYBOARD EQUIVALENTS
      All calculator buttons are also available from the keyboard.  The default
      bindings are shown below.

                  Return                 =



      You can rebind the keys to your liking using the X defaults file.  The
      action 'doKey("string")' makes the calculator behave as though the button
      labeled "string" was hit.  For example


                 <Key>Return:          DoKey(=)

      binds the return key to act as though the equals button was pressed.

RESOURCES
      heXcalc consists of a a vPaned widget ("wholePane") with two panes. The
      top pane is a label widget ("display"). The bottom half is a from widget
      ("buttonForm") holding the command widgets that make up the calculator
      buttons. The buttons are named in such that groups of buttons have the
      same name. This allows like buttons to be assigned similar colors with a
      single entry in the .Xdefaults file.  These groups are:

                       Name              Buttons

                 baseKey           dec, hex, oct, bin
                 controlKey  off, C, CE/C
                 evalKey           (, ), =
                 sizeKey           16, 32
                 signKey           sgn, usgn
                 memKey            Stro, Rcl, Clr
                 shiftKey          <<, >>
                 digitKey          [0-9a-f]
                 arithKey          +, -, *, /
                 bitKey            ~, |, &, ^
                 +/-               +/-


      Two actions are supported. "DoKey" (described above) and "Delete" with
      deletes the last digit button pressed.

BUGS
      Shift operations probably should have the shift count always interpreted
      as decimal.

      Overflow detection on input leaves something to be desired.
