XCalctool -- A scientific/programmer's calculator for Sun workstations
X
X Calctool is a windowed calculator suitable for Suns running SunOS
X3.0 or higher, utilizing SunWindows and SunTools. The code is relatively
Xstraightforward, and requires minimal modification to compile on most any
XSun system.
X
X A glance at the Makefile will show that you should make sure that FONTDIR,
XBINDIR, MANDIR, and MANEXT are correct for your site before making calctool.
X
X Calctool needs the font /usr/lib/fonts/fixedwidthfonts/gallant.r.19,
Xso make sure that this font exists.
X
X The man page should explain most things. Calctool is loosely based upon
XTI-type calculators, and uses an "Inverse" key to switch to alternate key
Xfunctions. Calctool allows alternate functions to be reached directly by
Xselecting keys with the middle mouse button, rather than the left mouse button.
XRead the man page for more details.
X
X Enjoy, and please send any bugs or comments to

X.SH NAME
Xcalctool \- desktop calculator
X.SH SYNOPSIS
X\fBcalctool\fP
X.SH DESCRIPTION
X.LP
X\f2Calctool\fP is desktop calculator which runs under \f2suntools\fP(1).
XUsers interact with \f2calctool\fP using the mouse and keyboard as
Xdescribed below. \f2Calctool\fP honors the standard window command line
Xoptions.
X.LP
X\f2Calctool\fP can be used as a scientific calculator, providing the
Xstandard trigonometric and transcendental functions, or it can be used as
Xa programmer's calculator, allowing bitwise manipulation of binary, octal,
Xand hexadecimal values. All internal values in \f2calctool\fP are maintained
Xusing double precision floating point.
X.SH "USER INTERFACE"
X.sp
X.SH "The Display"
X.LP
X\f2Calctool\fP presents the user with a keyboard and a display area. The
Xdisplay area displays the results of calculations, and a status line
Xshowing information about the current mode of \f2calctool\fP. The left portion
Xof the status line displays the operator stack, allowing the user to track
Xpending operations as \f2calctool\fP stacks them. The middle of the display
Xline shows the current trigonometric mode, either \*(lqDeg\*(rq, \*(lqRad\*(rq,
Xor \*(lqGrad\*(rq. To the right of the trigonometric mode, either \*(lqEE\*(rq
Xor \*(lqEng\*(rq will appear when the calculator is in scientific exponential
Xor engineering exponential mode. The right portion shows the current display precision,
Xindicating the number of decimal digits shown (in scientific mode) or the
Xnumber of bits shown (in programmer mode).
X.LP
XIn scientific or enigneering mode, the value in the display is presented in fixed point notation if it
Xis small enough, or is converted to scientific notation if not. In programmer
Xmode, the value is presented as a bit string in the appropriate base. The
X\f3Fix\fP and \f3EE\fP keys, below, control the precision and format of the display.
X.SH "The Keyboard"
X.LP
XThe various keys on the keyboard are, for the most part, self-explanatory.
XKeys are \*(lqpressed\*(rq by clicking the left mouse button on the key.
XSome keys also have inverted functions, which are accessed by first
Xclicking the \f3Inverse\fP key, and then clicking the desired inverse
Xfunction. Clicking the \f3Inverse\fP key causes the inverse functions
Xto be displayed. Those keys without inverse functions are grayed out.
X.LP
XA shortcut method is provided to access inverse functions. Clicking the
Xmiddle button on a key accesses its inverse function directly, without
Xpressing the \f3Inverse\fP key first. Pressing and holding the middle button
Xon a key will preview its inverse function; releasing the middle button
Xwill activate the inverse function.
X.LP
XSeveral keys on the keyboard have special functions associated with them.
XThese keys are:
X.IP "\f3Sto\fP, \f3Rcl\fP, \f3Exc\fP"
XWhen accessed with the left button, these keys access memory 0 of \f2calctool\fP.
XIf more memories are desired, they can be accessed by pressing the right
Xbutton on the desired key. A menu will pop up, showing the various memories
Xcurrently in use. In the case of the \f3Rcl\fP or \f3Exc\fP keys, selecting a memory
Xwill cause that memory to be recalled to, or exchanged with, the value in the
Xdisplay. The \f3Sto\fP key works in a similar manner, except that an additional
Xentry, \*(lqNew Memory\*(rq, is also provided. Selecting \*(lqNew Memory\*(rq
Xcauses a new memory to be created, containing the value in the display. Up to
X42 memories (0 through 41) can be created in this manner.
X.IP "\f3Fix\fP, \f3DRG\fP"
XThe \f3Fix\fP key is visible in normal scientific or programmer mode, while the
X\f3DRG\fP key is visible in inverted scientific mode. When accessed with the
Xleft and middle buttons, these keys cycle through the various display modes.
XIn scientific mode, the \f3Fix\fP key cycles through 0 to 12 digits, and floating,
Xprecision. This value determines the number of digits which follow the decimal
Xpoint in the display. In programmer mode, the \f3Fix\fP key cycles through
Xthe available bit widths, which for binary is 4, 8, or 16 bits, and for octal
Xand hexadecimal is 8, 16, or 32 bits. The \f3DRG\fP key cycles among the
Xdegrees, radians, and grads trigonometric modes, which determines how the
Xtrigonometric functions will accept and display their arguments.
X.IP
XEither of these keys cycles when clicked with the left button, and displays a
Xmenu when clicked with the right button.
X.IP "\f3Scientific\fP, \f3Binary\fP, \f3Octal\fP, \f3Hexadecimal\fP"
XThis large key cycles between the various calculator modes. Clicking with the
Xleft button cycles through the four modes, while the right button displays a
Xmenu of the various modes. When switching from one mode to another, the
Xdisplay is modified to reflect the new mode. The \f2internal value\fP of
Xthe display is not changed until that value is used. For example, if the current
Xvalue in the display is \*(lq14.5\*(rq, selecting hexadecimal mode will cause the
Xdisplay to read \*(lqD\*(rq. However, the internal value is still 14.5.
XReturning to scientific mode will restore the display to \*(lq14.5\*(rq. If,
Xwhile in hexadecimal mode, 1 was added to the display, (displaying \*(lqE\*(rq),
Xreturning to scientific mode would display \*(lq15\*(rq, since hexadecimal mode
Xtruncated the display before using it.
X.IP \f3EE\fP
XThis key places the calculator in exponential mode, which causes all results
Xto be displayed in scientific notation. In scientific mode, normal
Xscientific notation is used. In engineering mode, the exponent is
Xadjusted to a multiple of three. To return to normal display mode,
Xclick \f3Inverse\fP \f3EE\fP. This key also allows the user to enter
Xexponents when keying in a value. Clicking \f3EE\fP once allows the user to
Xenter the exponent value. Clicking again returns the user to entering the
Xmantissa.
X.IP "\f3Erase\fP, \f3Clear\fP"
XThe \f3Erase\fP key erases the currently displayed value and replaces it
Xwith zero. The \f3Clear\fP key erases the display, the internal value stack,
Xand the internal operator stack. The \f3Clear\fP key can be accessed by
Xclicking the \f3Erase\fP key with the middle mouse button.
X.SH "Typing Values"
X.LP
XInstead of clicking keys, the user can type values directly on the keyboard.
X\f2Calctool\fP will recognize the digits \*(lq0\*(rq through \*(lq9\*(rq, and \*(lqA\*(rq through \*(lqF\*(rq in
Xhexadecimal mode. In scientific mode, the \*(lqE\*(rq key acts like the
X\f3EE\fP key
Xand the \*(lq.\*(rq key acts like the decimal point key.
XThe \*(lq+\*(rq, \*(lq-\*(rq, \*(lq*\*(rq, and \*(lq/\*(rq keys correspond to addition, subtraction,
Xmultiplication, and division, and \*(lq(\*(rq, \*(lq)\*(rq, and \*(lq=\*(rq perform the expected function.
XIn addition, the \*(lqS\*(rq, \*(lqR\*(rq, and \*(lqG\*(rq keys correspond to the store, recall and
Xexchange functions. The \*(lqX\*(rq key is equivalent to \*(lq*\*(rq, and carriage return and newline
Xact like the \*(lq=\*(rq key.
