This calculator is kind of different. Also, it uses RPN to build expressions, not just do calculations, which is a little different than the way HP calculators worked it's arguably much better - but some people just want what they know. On the other hand, if you're willing to try something different, this calculator does a pretty good job of combining the elegance of RPN with the friendliness of the best algebraic calculators.
At least it's a functional RPN calculator, although it's missing some key functionality pun intended. I would suggest that the "Esc" key should be "Clear Stack". This should probably be assigned to "Backspace" or potentially "Delete". Thanks for the feedback. I'll put more keyboard support into the new release coming out next month.
If you have more suggestions feel free to email me at john linstrum. I haven't truly explored this calculator yet. Nowadays, I just need a handy calculator app on my laptop that doesn't do unexpected things. So far, this app fits that need. I look forward to learning its other features as I go. Good work! I love the app except when I hit the ". Thanks for the bug alert; I put a fix into the latest release.
If you have any other problems let me know at john linstrum. My first impression is good. I'll update my review if I run into any problems. But two thumbs up for now! I really like the large easy to read display. Also the text areas shows the previous steps, This makes it easy to find any errors in my formulas.
I've used several RPN apps and this is my favorite. Nice implementation of RPN, with a bit of a twist since the calculations are displayed in textbook format. Kind of simple but good. Also nice that's it's free with no ads.This calculator is kind of different.

On the other hand, if you're willing to try something different, this calculator does a pretty good job of combining the elegance of RPN with the friendliness of the best algebraic calculators. High possibilities, low information.
After invoking the formula and opening the round bracket I get the message "user error: the function needs 3 entrances. OK, I know that and cannot believe it to be an error. No further help available. Congratulations for thinking RPN further! This is a really fine marriage of good old HP style and modern capabilities. I am freshly into this app still, but it already has replaced my default calculator on my workstation. And I surely will go through everything it has to offer. If the app will ever get programming capabilities, it is a well worthy replacement for the HPC apps around.
Thank you! Supplement after using it some time: The "sets" feature is just extremely useful for me. Thanks for the font-scaling update! Fonts scale very well now on PCs and tablets. Thank you for your review and the helpful suggestions you sent me via the feedback feature.

Risk Priority Number RPN is a measure used when assessing risk to help identify critical failure modes associated with your design or process.
The RPN values range from 1 absolute best to absolute worst. The graphic below shows the factors that make up the RPN and how it is calculated for each failure mode. Examples of Severities.Java How-To : RPN Calculator using Patterns
Examples of Occurrence values. It is a numerical subjective estimate of the effectiveness of the controls to prevent or detect the cause or failure mode before the failure reaches the customer.
The assumption is that the cause has occurred. Examples of Detection values. Although it is true that larger RPN values normally indicate more critical failure modes, this is not always the case.
For example, here we have three cases where the RPNs are identical, but clearly the second case would warrant the most attention. As a general rule, any failure mode that has an effect resulting in a severity 9 or 10 would have top priority. Severity is given the most weight when assessing risk.
Next, the Severity and Occurrence S x O combination would be considered, since this in effect, represents the criticality. Below is another RPN example reminding us that we need to be careful not to assess risk purely based on the RPN values. Here, the failure modes with the lowest RPN values are actually the most critical.
Be careful to not just establish "threshold values" for RPNs when assessing risk, as this could lead you to make costly mistakes.

Below we see that 1 is most critical even though it has the lowest RPN value, then 2, and then 3. In summary, always address high severity failure modes regardless of their overall RPN values. Effective FMEAs. Identifying Failure Modes.You seem to have CSS turned off. Please don't fill out this field. RPNcalculator Web Site. Very nice functionality; it is now my main Windows calculator.
I find it it's design somewhat too bulky and colors are not ideal, but this is of course minor points. Overall, very good work; probably best RPN calculator currently available for Windows.
Good looking RPN calculator, but it comes up with inaccurate numbers some times for example, Emails to developer bounce, so it may be abandonware at this point.
This is excellent. No need to look for anything else except version 2. Indicators for number system and angular units not working for me on Win7. Symbol on multiply key is identical to x on variable "x" key. Minus sign on subtract button is a hyphen.

An RPN Reverse Polish Notation calculator allows numbers and operations to be entered without parentheses or an equal key. RPN is based on a stack. Unary operations such as log and sin pop a number from the stack, apply the operation, and push the result back on the stack. The layout of the keys appears twice in the MainPage.

The command line is nice. The infinite? The stack is not correctly represented in relation to the command line. I would rate the application 3. The 'Undo' command works well, but it is an unconventional name. I must stress again that if the application is meant to resemble an HP calculator the stack has to be inverted; if not, the command line should be moved to the top of the display.
This is a quite usable RPN calculator with a large infinite? I realized that you have the calculator in Base 8 instead of Base 10!
Makes CNET's installer seem downright pleasant. The calculator itself is OK but has a fixed stack of 4, which makes it less useful. Hopefully the author will update this one day. It runs fine under Win bit, but I couldn't get the help file to open by clicking Help. I could open the help file directly from the install folder though A few more keyboard shortcuts would be a big help.
Customizable shortcuts would be really great. I would recommend this to someone looking for a small, free, application that allows you to do basic RPN calculations.
Sometimes genius is in simplicity. I get the error message: invalid operation.
Strangely enough, I have the latest Microsoft. Quick, easy, useful tool. Installed perfectly.
Although i have to say i like the styled functional look of a HP design, as seen in another RPN calculator. The command line is separate from the stack, which is excellent. The window is resizable. There is no Drop button keyboard shortcut, no thousands separator, does not use system comma, strangely the stack is loaded from the top. This calculator is large, resizable, and the colors can be adjusted.
I wanted one because the Windows calculator was too small and awkward for me. I haven't used RPN since and will not be doing advanced calculations on it. So I can't speak to the some of the issues addressed in other reviews.Perform, save, and print various computations with a complete help system and tips. RPN Calculator is a calculator that uses the Reverse Polish Notation method of user interaction, which is typically popular with people who deal with financial, engineering or other technical problems.
