RPN Engineering Calculator™
The RPN Engineering Calculator™ (REC) is software that
lets you choose between 6 different calculators at the Click of your
mouse, and 14 discrete calculators for the more complex functions.
This RPN Calculator offers a choice of more than 250 solutions and
thousands of conversion possibilities with six unique
keypads. A "Tip of the Day" is displayed when you start the
program (it can be turned off), It has a complete help system and individual tips for all but the most ordinary functions.
The calculator has a Running Tape Display showing all entries
and solutions for each session as well as the operation just performed,
or the units (Hz, °, Hy, etc.) of the result.
You can choose between fixed point, scientific, and engineering
notation, and select degrees, radians, or grads as the situation requires.
Keyboard entry is
optional for most of the common functions.
You are able to save
the contents of the calculator, the Running Tape Display, the Register
Stack, all necessary data required to be able to take up where you left
off prior to saving. You
can print the contents of the Running Tape Display and you can
double-click on any number in the Running Tape Display or the Stack
Display to copy it to the
x-register.
The RPN Engineering Calculator™ uses an entry register (input window), a working register, referred to as the
x-register (x-reg) and a holding register, referred to as the y-register
(y-reg) and an almost unlimited stack.
Following are links to short descriptions of the available functions on each of
the six keypads, Click on the link to view the description..
The Standard keypad has many of the standard functions available on
most Scientific Calculators, this
calculator takes it
somewhat further!
The Engineering keypad has several
functions to help the engineer.
The Binary keypad
is used to
manipulate binary integers of any word size from 4 to 64.
Use
the Magnetics keypad to calculate various solutions dealing
with the design of transformers and
inductors.
The Trig Keypad, as might be
expected, most of these functions deal with
trigonometry.
The final RPN Engineering Calculator™ keypad,
the Convert Keypad consists of many different
conversions, there is also a Physical Constants ('K')
function and a ('val') function that calculates the value of Resistors,
Capacitors, and Inductors, based on the color or numeric code on the
component.
Some of the functions available while in most keypads are:

the calculator, use your web browser's Back button to return here.)
View lets you toggle between the
standard interface (shown at the right) and the enhanced
view, Click for more information. Two other views
are available, one that lets you view just the y-register and the other
that lets you view the memory and lastx registers.
There are many functions that can be accessed
using the keyboard, click to see a handy,
printable table.
The Cursor
keys offer different methods of changing the active Keypad.
Drop - deletes the current value in the x-reg, placing it
in the last x register, and Drops the number in the y-register down into the
x-register.
x<>y - exchanges the values in the x and y
registers.
Lastx
- retrieves the last number that was used in a calculation.
STO (copies the number in the x-register into one of the four memory registers,
m), two of the memory registers (m3 and m4) can be used with the math
buttons (÷, X, -, and +) to perform register arithmetic
(m3) or use it (m4) as a constant.
CHS - changes the sign of the mantissa or exponent of the number
being entered. (This function is replaced by the Mod function in
the Binary Keypad).
EEX - to
enter number multiplied by the power of 10.
File Menu
Available, via the File menu, is the ability to
copy and paste the x-reg to and from the Windows Clipboard (Ctrl+C and
Ctrl+V will also copy and paste). Save your favorite default settings: Keypad; View option; Degrees,
Radians, or Grads; display type (FIX, SCI, or ENG) and number of digits, as well
as the previously mentioned Save (and Retrieve) Running Tape feature,
and Print the contents of the Running Tape Display along with the
contents of the Stack.
