Android's calculator also has the history, invoked by pulling down on the display part. (Perhaps obvious to everybody here, but after the discussion on how the memory function is unclear to people, I'm not so sure.) Also that history is saved between launches, which happens to be extra useful for me.
- contravariant 4y agoOh, that is useful. Now if only I could calculate the log of something by pressing 'log' that would be nice.
- tzot 4y agoI think that my Android phone (a Chinese model with Android 11 Go) has the Android calculator, which IIRC was based on the old SGI Irix calculator. If to the right of the 4 basic operators +, -, ×, ÷ you have a vertical strip (greenish in my case), you can slide it to the left and have access to various other operators/functions, including log. Being based on the old SGI calculator, you can also slide any result to the left to get as many digits after the decimal point as you like. e.g. slide in the extra ops, press π, then start sliding the 3.1415… result.
- aasasd 4y agoI think the guy was saying that you have to surround an expression with ‘log()’ to get the logarithm—which is inconvenient when it's a result of previous calculations and you have to shuffle the cursor around. Can't just slap ‘log’ and have the current expressions logarithmized. However, seeing as the calculator allows writing expressions with multiple operations, just shoving everything on the screen into ‘log()’ would be unreasonable, as one might want to provide the exact place for the logarithm themselves—so I guess the app does the most reasonable thing it can.
- paledot 4y agoNo, I've been using the Android calculator for years and never realized that it could do that. This is the problem with "clever" UX...
- wolpoli 4y agoI never clued in to the fact that the little bar below the calculator screen meant that you could pull it down to show history either.
- aasasd 4y agoCoincidentally, history is also available via the three-dots menu =)
- paledot 4y agoSpeaking of cryptic UX, though that one at least is standardized nonsense.
- crumpled 4y agoHistory is nice. I do wish it had the memory buttons.
- aasasd 4y agoYou can just select and copy, and then paste. The whole expression is editable as a line of text.
- crumpled 4y agoThanks to this post, I played with the history and discovered that if you tap an expression in your history, it becomes the current expression.
