HP caclulators in general use an unusual key-command ordering,
called Reverse Polish Notation (RPN), also called postfix
notation.  If you窶决e not familiar with RPN, you should get a
real HP calculator and read the manual, or you can hack on
this version to discover how it works for yourself.  In a
nutshell, RPN means you must enter the numbers that you want
to operate on first, and then push the operation key.

For instance, to calculate the value of (8-3)*4, the keys you
would push would be 8, ENTER, 3, -, 4, *.  When you push the
ENTER key, the 8 gets copied from the 窶忸窶 register to the 窶忱窶
register (and the rest of the 窶徭tack窶, which you can窶冲 see,
gets pushed up).  When you hit 窶œ-窶, the number in the x
register is subtracted from the number in the y register, and
the result, 5, is placed in the x register.  (The rest of the
stack moves down.)  To multiply this by four, all you need to
do is enter the 4 (because the 5 is already there), and hit
the multiplication key.  Try it!

The remainder of this text describes each of the functions on
the calculator keys.  Most of them act exactly like their
counterparts on an HP calculator.

窶｢ Alternate Keys:

.00 f or gold
   Push this key to get access to the functions in gold above
   each key.  A small up-arrow will appear in the display.
   You can also hold down the shift key for the same effect.

.01 g or blue
   Push this key to get access to the functions in blue below
   each key.  A small down-arrow will appear in the display.
   You can also hold down the option key for the same effect.

窶｢ﾂ Stack Functions:

.02 clear registers
   Clear Registers resets the entire stack to 0.  It does not
   affect the lastx register or stored locations.

.0304 rotate stack
   These functions rotate the four registers up and down.

.05 exchange
   Exchanges the x and y registers.

.06 clear x
   This key clears the x register whether you窶决e inputting
   or not.

.78 enter
   Shifts the stack up, making a copy of the x register.  The
   contents of the register at the top of the stack are lost.

.08 last x
   Recalls the x register value from the most recent operation.

窶｢ Numeric Input:

.1011121314151617181907 input
   Start entering a number by typing it.  An underscore will
   follow the number while inputting mode is in effect.  End
   the input of a number with the ENTER key or a function.

.202122232425 hexidecimal input
   You can enter hexidecimal values A (10) through F (15) with
   these keys.  This version no longer requires you to hold
   down the shift key while typing the key equivalent.

.73 pi
   This key inserts the value of pi into the x register, just
   as if you had typed it yourself.

.26 exponent
   Push this key to input an exponent, e.g. 1.34e-10

.27 backspace
   This key backspaces one character if you are currently
   inputting a number, or clears the x register if you窶决e not.

.28 change sign
   Use this key to change the sign of the number in the x
   register.  If you窶决e entering a number, you can also use
   this to change the sign of the exponent.

窶｢ Display Format:

.2930 hexidecimal and decimal bases
   These keys change the base mode so that all numbers are
   displayed in hexidecimal or decimal format.  Both hex and
   decimal numbers are shown in floating point format,
   depending on the last FIX or SCI request.

.31 binary base
   Changes the mode of the calculator to display numbers in
   binary format.  Only the integer part of the number is
   displayed, although the full precision is kept internally.
   Numerals up to 64 bits long (ﾂｱ9.2e+18) can be displayed.
   Numbers larger than this are shown as <Too big> in binary.
   In FIX format, the actual number of digits with an optional
   minus sign is shown.  In SCI format, all 32 or 64 bits of
   a two窶冱 complement form are shown.  Binary numbers are
   always entered in FIX style format.

.32 scientific notation
   Sets display to scientific notation (all numbers shown in
   N.NNNNNeﾂｱNNN format).  You get to select the number of
   digits after the decimal point, 0-15.  Entering a decimal
   (.) for the number of digits causes as many as possible to
   be shown, with trailing zeros removed.

.33 fixed point notation
   Sets display to fixed-point notation (standard NNN.NNN
   format).  You get to select the number of significant
   digits as before.  Any number too large or too small for
   this format will be shown in scientific notation.

窶｢ Basic Functions:

.34 add
   Adds the numbers in the x and y registers.

.35 subtract
   Subtracts the number in the y register from the number in
   the x register and returns the result into x.

.36 multiply
   Multiplies the y register by the x register.

.37 divide
   Divides the number in the y register by the number in the
   x register and returns the result into x.

.38 remainder
   Modulo gives the remainder after dividing the number in
   the y register by the number in the x register to yield a
   whole number.  This is equivalent to y - int(y/x)*x.

.39 multiplicative inverse
   Calculates the multiplicative inverse of the number in
   the x register.

.40 power
   Calculates the power of the x register to the base in the
   y register.

.41 square root
   Calculates the square root of the value in the x register.

.42 square
   Calculates the square of the value in the x register.  You
   can also type ENTER, X to do the same thing.

.43 percent
   This key returns the percentage in the x register of the
   value in the y register, but does not remove the value in
   the y register.  So to calculate a 15% tip, you could type
   15 % +.

.44 absolute value
   Calculates the absolute value of the x register.

.45 fraction
   Returns the fractional part of the value in the x register.

.46 integer
   Returns the integer part of the value in the x register.

窶｢ Trancendental Functions:

.474849505152 trigonometric functions
   These keys calculate the corresponding trigonometric
   functions on the numbers in the x register.  Angles are in
   degrees or radians, depending on the state shown in the
   display (RAD or DEG).

.5354 angle measurement
   Change the angle mode of the calculator to radians or
   degrees, respectively.

.5556 angle conversions
   Same as RAD and DEG, but also convert the number in the
   x register from degrees to radians, or radians to degrees,
   respectively.

.57 natural log
   Calculates the natural logarithm of the x register.

.58 natural exponential
   Calculates e (the natural logarithm base) to the power in
   the x register.

.59 base 10 logarithm
   Calculates the base 10 logarithm of the x register.

.60 base 10 exponential
   Calculates 10 to the power in the x register.

窶｢ Statistics Functions:

.61 clear statistics
   Clear Statistics resets the statistics registers.  The
   statistics registers on this version have names that begin
   with 窶徭tat窶, as in 窶徭tat xx窶.

.62 add statistics
   Add the x and y registers to the statistics database.  Also
   places n (the number of point inputted) in the x register.

.63 remove statistics
   To correct a mistake in statistics data, enter BOTH the
   x and y incorrect values, then push this key, and re-enter
   the correct x and y values.

.64 average
   Average puts the mean of the x and y statistics into the
   x and y registers, respectively.

.65 standard deviation
   Standard deviation puts the standard deviation of the x
   and y statistics into the x and y registers, respectively.

窶｢ Probability Functions:

.66 factorial
   Calculates the factorial of the number in the x register.

.67 choose
   Choose gives the number of possible sets of x elements
   taken from a set of y elements.  It窶冱 equal to y!/x!(y-x)!.

.68 permute
   Permutations gives the number of permutations of y elements,
   when choosing x at a time.  It窶冱 equal to y!/(y-x)!.

.69 random number
   Returns a random number between zero and 0x4FFF FFFF.  This
   number is also put into the memory slot named 窶徨andom窶.

窶｢ Memory Functions:

.70 calculator reset
   Reset clears all of the calculator窶冱 memory locations, as
   well as the stack.

.7172 store and recall
      Stored memory locations are accessed by name.  Names can be
   up to 13 characters long, and must not begin with a space,
   +, -, *, or /.  A list of names appears on the side of the
   calculator.  You can double click the name to select that
   register, or type the name yourself.  Pressing tab at any
   time will try to complete what you窶况e typed. Typing one of
   the four basic operations (+, -, *, ﾃｷ) before you input the
   name of the memory adds, subtracts, multiplies, or divides
   the destination by the source.

.80 delete
   If you decide that you won窶冲 need a particular memory
   location ever again, you can remove it with this function.
   You can窶冲 delete the original statistics and random
   locations.

窶｢ Miscellaneous stuff

.81 zoom
   This function shrinks the calculator to icon size on the
   desktop.  When you want it again, just click the small
   calculator and it will zoom back to full size.  This is
   faster than quitting and restarting.  You can also
   double-click the top of the calculator to zoom it.

.09 off
   Turns the calculator off (identical to choosing quit in the
   file menu).  The window position, memory, and stack are
   remembered between runnings of the calculator.

.74 about
   Gets you here.

.75767779
   These functions haven窶冲 been written yet.  They do not
   appear on the calculator keys, so don't try assigning key
   equivalents for them in the key caps editor. Yet.

There are plenty of blank spaces on the keys, so if you think
of anything you窶囘 REALLY like to see on the calculator, write
me at [e-mail], and I窶冤l try to put it in on the next
version.
