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 left‐
most button on the pointer). These can be changed using the transla‐
tion manager.
button Usage: Most of the buttons are self explanatory (for C program‐
mers). 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.

You can rebind the keys to your liking using the X defaults file. The
action 'doKey("string")' makes the calculator behave as though the but‐
ton 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 wid‐
get ("buttonForm") holding the command widgets that make up the calcu‐
lator 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.

Shift operations probably should have the shift count always inter‐
preted as decimal.
Overflow detection on input leaves something to be desired.
