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.

Keyboard		Button
	  (			(
	  &			&
	  ^			^
	  )			)
	  ^c			off
	  H			hex
	  O			oct
	  D			dec
	  B			bin
	  R			Rcl
	  S			Sto
	  s			16
	  l			32
	  +			+
	  -			-
	  *			*
	  /			/
	  %			%
	  >			>>
	  <			<<
	  0			0
	  1			1
	  2			2
	  3			3
	  4			4
	  5			5
	  6			6
	  7			7
	  8			8
	  9			9
	  a			a
	  b			b
	  c			c
	  d			d
	  e			e
	  f			f
	  ^h			Delete last digit (Not available via button)
	  Delete		Delete last digit (Not available via button)
	  =			=
	 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.
