0x29A – It’s only a number

Last week’s ToW was the six-hundimagered, three-score and fifth, and while this week’s is one more, it’s probably best if it’s not mentioned. As well as being called out in a certain old book, said number also features greatly in legend, light musical entertainment and popular fiction.

Other numbers attract a certain amount of superstition – some tall buildings don’t have a thirteenth floor, for example, and even big companies like Microsoft have been known to clip_image002dodge bad luck by not shipping a v13 of a product (like Office – look at the File | Account | About dialog in any Office app, and you’ll see the version number – Office 2007 was v12 and Office 2010 was v14). Some cultures don’t much like the number 4 or 14 either.

clip_image004One numerically interesting but easily overlooked app in Windows 11 is the venerable Calculator. Start it by pressing the Windows key and entering calc, or if you’re truly blessed, you might even have a physical button on your keyboard. The app starts in whichever mode it was last run – by default, a simple calculator with the same kinds of functions that were common on the popular pocket calculators of the 1980s.

But look at the hamburger menu on the top left and you’ll see so much more – from Programmer functions to convert numbers from clip_image006one clip_image008base to another (so you can decode hex error messages or “funny” binary t-shirts*), to a whole array of converter functions which let you quickly change currency (at the current rate) or transform from one measurement standard to another.

There’s a neat date calculator too, so you don’t need to resort to using an Excel formula to count how many days there are between two dates.

Back in Standard mode, you’ll see the history of your calculations on the right side, and you can use the Memory functions to store multiple numbers for future use; much better than the old one-and-done M- clip_image010M+ and MR buttons on a pocket calc. There’s also a mode which keeps the calculator window on top of others, even if it isn’t the active window at the time.

If you have a full-sized keyboard, you’ll also probably have a NumLock key – that turns the numerical keypad on the right side on and off. In the early days of the PC, smaller keyboards didn’t have separate cursor keys, so these were sited on the keypad. In order to use these cursor functions – and the others, often doubled-up PgUp / PgDn etc – you’d switch NumLock off. And then swear when you went to use the numerical pad to quickly enter a number into some DOS application, only to find you’ve moved the blinking cursor around instead.

*convert each of the 8-bit binary numbers in the t-shirt to decimal; assuming the decimal number is the ASCII code corresponding to a letter, open a new blank doc in Word, and holding down the ALT key, enter the decimal number on your numeric keypad. Oh, if you’ve only got a laptop with no separate Numlock/keypad, bad luck.

545 – Calculator Short Cuts

clip_image001

For what most people would think of as a simple application, Windows Calculator has had a reasonable chunk of attention on ToW over the years – back in 2012, #90 uncovered some of the groovy updates that were coming in the then-soon-to-be-forthcoming Windows 7. Did anyone actually go to a Launch Party?

clip_image003CALC has grown to include lots of other features than simple arithmetic – adding scientific functions, programming functions (for all those times when you need to multiply in octal, for example) and more..

clip_image005

Calculator was reimagined as a Modern App, and has added numerous extra features accessed via the hamburger menu – such as Date Calculators that will show the time difference between two dates – or numerous converters, some static (eg. length, weight – measures that don’t tend to change) and others dynamic, like currency conversion rates. A visual refresh arrived with a colourful new icon and some other graphical tweaks.

There are some neat shortcut keys as well – if you press ALT+H, the hamburger menu will show; to jump to another option, press ALT and another letter or number than corresponds to the appropriate option. To find out what the options are, just press ALT and the letters/numbers will be displayed. Once you know, though, you could press ALT+H and holding ALT, press C for currency. Whichever mode you’re in, pressing ALT+1 will take you back to Standard calculator.

If you have a recent Microsoft keyboard there may even be a dedicated calculator key that will launch the calculator app (also available via START+R | CALC | Enter) but if you’d rather use that button for a more commonly needed app – Teams maybe – then you can install the Mouse & Keyboard Center software, to re-map the hardware button to run a different application.

clip_image007If you want to be particularly fly, you could set up macros to chain other key presses together, or even have app-specific functions on that key; so pressing the Calculator button might launch Teams or bring it to the fore, then pressing it again could do something else within Teams – press CTRL+1 to jump to the first icon in the side bar, for example.

One final calculator tip – each of your calculations are preserved – just click the icon or press CTRL+H to clip_image009open History and then right-click any of the previous results to add them to the clipboard.
