An adding machine? How quaint. You’ll see them in movies and on TV shows whenever someone travels back in time. A few of us educated in the last century know about adding machines before they became calculators.
As a Mincey I’m gene-bound to collect adding machines and calculators. My family had more than a few accountants in the past so we have some of those one-armed slot machine-like math bandits in the attic and probably somewhere in the garage. If you like, use, or need a modern calculator, here’s a good one because it works and runs everywhere.
For Fun And Profit
Back a few decades ago I bought one of those inexpensive electronic watches with a built-in calculator. Think about the changes since then. Today, my watch can make phone calls, handle email and text, receive alerts and notifications, play games, display the news, track my heart rate and exercise and much more.
Calculators haven’t changed much in recent years except they do more, do it more easily, cost less, and now, thanks to the internet, can sync up calculations between devices. On my list of good calculators is CalcTape, a slightly more feature laden electronic calculator that runs on Mac, iPhone, iPad, and even Windows and Android devices.
Looks inviting, right?
That’s the whole idea. A calculator should be inviting but it should have most of the bells and whistles we expect of numerical calculators in the 21st century.
- Enter many calculation terms in one turn and still keep an overview – like on an adding machine / desktop calculator.
- Change any term afterwards and CalcTape will refresh the whole calculation automatically.
- Use intermediate results to check and structure your calculation.
- Comment your calculation terms, to give sense and context to it.
- Save your calculations into files. Open the files later and you can change the calculations. CalcTape will refresh the whole calculation automatically again and again.
- Use your existing CalcTape files as templates. Do similar calculations and play different scenarios.
- Use the programmable buttons e.g. for fast TAX calculations.
- Scratchpad for every-day calculations is being saved automatically.
- Put calculations side by side for comparison.
- Work with variables and generate “speaking” calculations.
- Define as many programmable keys as you like.
- Use parentheses and trigonometry when defining variables.
- iCloud support (Mac OS 10.10 and higher). Sync your calculations with iPhone and iPad easily.
- CalcTape masters the four basic arithmetical operations, exponentials, and percentage calculations.
- CalcTape for MacOS requires MacOS X 10.9 or higher.
As much as any of the features on the list above the three that are most important are, 1) accessibility– you can see what you’re calculating on the tape as you calculate and it’s side-by-side, and 2) iCloud support is built-in so a calculation started on a Mac can show up in a few moments on an iPhone or iPad, and, 3) yes, CalcTape runs on multiple devices so you get the same features, look and feel wherever you go to, well, calculate.
Is this as feature laden at my favorite, PCalc? No. But it’s close.
