PCalc 1.7 just hit the App Store, and it is—despite the meager 0.1 increment in version number—a major update to the iPhone's premier calculator application. The new and/or improved features (in order of importance1) are:
- Easier to Read digits that are truly easy to read at all sizes.
- Multiple memory locations.
- Buttons for Stack Clear (SC) and Memory Clear (MC).
- A display that can show up to four lines of data.
- A faster startup.
- More logical Enter behavior.
- More unit conversions.
- A setting that prevents the calculator from going to horizontal mode when the phone is rotated.
We'll look at each of these features in turn. Let me first point out that I've written several earlier posts on PCalc. Most of what I wrote in my series of Definitive Posts on PCalc (part 1, part 2, part 3, and part 4) and my descriptions of the version 1.5 and version 1.6 updates still holds and won't be repeated here. This will be just the new stuff. I should also mention that I use PCalc's RPN mode exclusively—improvements to its algebraic mode fly under my radar, and I can't comment on them.
Easier to Read digits
PCalc can display digits in a manner reminiscent of older physical calculators, imitating either LCD elements or chunky pixels. Because I am in my late 40s and have the faltering eyesight of middle-age, I have always prefered the Easier to Read digits, even though they weren't as easy to read as i would have liked.
Actually, the digits themselves were pretty easy to read, it was the tiny comma and decimal point that I had trouble with. James Thomson, PCalc's developer, bulked up the punctuation several point releases ago, which worked pretty well; but when he later introduced the two-line display, the punctuation shrunk back down to a size I found hard to see.

But with 1.7, Thomson has introduced fonts with big, robust commas and decimal points that aren't squeezed tightly in between the numerals.
The new display can pass the most stringent of visibility tests: that of a tired middle-aged man trying to do a few calculations on a late night flight.
Multiple memory locations
PCalc has always had a memory slot, and it's always had a stack that can be loaded up with lots of values. But most serious scientific calculators have serveral memory slots that are quickly addressable. Now PCalc joins them with ten memory slots, labeled 0–9. To store a value in memory you
- Type in the number.
- Press the M in button. Note how most of the buttons are dimmed; pressing them has no effect.
- Press one of the digit buttons.
The value is now stored in that memory slot. To retrieve a value from memory, you

The value is now stored in that memory slot. To retrieve a value from memory, you
- Press the M re button.
- Press one of the digit buttons.
The value will be copied from memory and pushed onto the stack.
NB: if you retrieve from a memory slot that hasn't had anything stored in it, zero will be pushed onto the stack. As I consider zero to be distinctly different from empty, I see this as a flaw. Fortunately, it's a flaw that does no damage. No items on the stack are destroyed by errant zero, and you can always return to the state before the inadvertent retrieval by Dropping the zero.
New Clear buttons
After several calculations, my stack is usually cluttered with old results, and it would be nice to blow them away with a single command. PCalc has the AC (All Clear) button, but pressing it has the unfortunate effect of clearing the memory in addition to the stack. This is an even more destructive operation now that there are 10 memory slots. Fortunately, PCalc 1.7 comes with a new SC (Stack Clear) button that will clean your stack while leaving your memories intact. It's accessed through the 2nd key.
For you Phil Dick fans, 1.7 also has an MC (Memory Clear) button that does just the opposite: erases all your memories while leaving your stack in place.
Multi-line display
PCalc has had an optional two-line display since version 1.2. Now you can chose to have up to four lines in the display, and the lines don't have to be values on the stack. The settings let you choose from many options.
Right now I'm using a three-line display of the stack.
Faster startup
4.3.1 Update
If you follow James Thomson on Twitter (@jamesthomson), you know that he spent a lot of time working on PCalc's code to get it to launch more quickly. He succeeded. While PCalc certainly doesn't start as quickly as Apple's standard iPhone calculator, it's become quite peppy. And it presents a cute aphorism to amuse (i.e., distract) you as it gets going.
There are many of these, all with a math or calculator theme.
New Enter behavior
Turning on the HP48 Style RPN option (it's in the Advanced settings) eliminates a behavior that's been bothering me for ages: the duplication of the x-register into the y-register when the Enter key is pushed. Here's the scenario:
- Start with an empty stack.
- Type in a number, say 42. The 42 goes into the x-register.
- Press Enter. The 42 gets duplicated and is now in both the x-register and the y-register.
This is batty. Pressing Enter should just enter it (hence the name) in the x-register—there shouldn't be a second copy of the value in the next stack position. I know that some calculators act this way, but that doesn't make it right.
If you turn on the HP48 Style RPN setting, PCalc 1.7 does the right thing: it enters the number in the x-register and waits for you to type another number before pushing the entered value into the y-register.
New unit conversions
There are now US and UK versions of the teaspoon, tablespoon, and fluid ounce so US cooks aren't confused by a cup with 8.11537 fluid ounces.
Locked orientation
The new Do Not Rotate setting will lock PCalc in portrait mode, which can be handy if you find yourself holding the calculator in a variety of orientations as you move around, write, adjust an instrument, etc. Locking isn't a big deal for me, but I can see where it would be very useful for some people. Tune sweeper 4 13.
Pcalc 4 3 12
It should be noted that you cannot lock PCalc in the horizontal mode. Although you can turn on the Do Not Rotate setting while the calculator is horizontal, it will shift to portrait mode the next time the calculator is turned vertical and will then be locked in that position.
Finally
I bought PCalc at version 1.0.x, and it's been my calculator ever since. I use it more than my physical HP 35s calculator, even when I'm at my desk and the HP is within reach. It's annoying that the 35s refuses to mutate when I press the ↰ and ↱ keys.
In order of importance to me, that is, which is all that matters. ↩

4.3.1 Ipsw
The Red-Bag Project Calculation Validation software or short PCALC is a software application for the validation of piping component and pressure equipment calculations.
The PCALC application can be used to study the code calculations for different design conditions, materials of construction and component dimensions. The tool is used for engineering training as conducted at InIPED, the International Institute of Plant Engineering and Design. Reallusion cartoon animator 4 02 0627 1 pipeline block.

The application has in addition to regular calculation reports an unconventional output: it can show a detail report how every formula is passed and what the input/output is. This is very useful when for example an iteration is done to get a solution. The validation of each calculation is a separate report with a summary and the detail in- and output.
The dimensions entered are shown in a dimensional sketch to scale. The sketch can be exported to DXF format for further use in a CAD application. The sketch has a tool to measure dimensions when the engineering is working on the calculations.
The PCALC application is made for Notified Bodies, Authority Approval Companies and code calculation development.
- Details
Proper engineering calculations include the validation of the dimensional input of the pressure components being calculated. The assessment based only on values is sometimes difficult due to interpretation or just the amount of dimensions to be checked. The most efficient assessment is done to use a sketch representing the dimension input to scale to the user.
The dimensions entered in PCALC are therefore shown in a dimensional sketch to scale. This sketch can be exported to DXF format for further use in a CAD application. The sketch has a tool to measure dimensions working with the calculations. The dimensions can be checked in the CAD application but also the calculated material and pressure areas, which are regularly used in the calculations.
- Details
The PCALC application will concentrate on ASME and EN code calculations. This calculations will be completed first. However depending the requirements of our customers we can start parallel development of calculations or calculation codes as per customer requests.
