Reading this article and the thought process behind it reminds me of this almost-10-year-old comment I made about how they actually work: https://news.ycombinator.com/item?id=9456444 https://news.ycombinator.com/item?id=9456444 Selecting an operator loads this value into the accumulator and makes room for the second operand to be typed in. Here is where I think the first mistake was made; if you observe the effect of repeatedly pressing '=', that obviously does not clear any registers, but merely repeats the last operation. But there’s more to the story: it’s actually a side effect of a little-known “K-constant” feature that retains one of the previously-entered operands and the operator, and lets you vary the other operand. I haven't used any 4-function calculator that behaves like this; instead, I get (without clearing): 2 + 1 0 = 12 5 = 22 0 = 32

Apple's recent iOS Calculator update broke this entirely and now = multiple times does nothing :/.

  those fuckers. If windows wants to add this as a success where Mac has failed, it still works in their calculator app.

    Windows also innovated from TTC to TTCC! (Time to Candy Crush, instead of Time to Crate.)

  This is fixed in the latest beta, which is probably going to ship next week or thereabouts.

  iOS calc sometimes registers a press but not a release(?) and a key gets stuck in "pressed" state and doesn't count as an input. Many years issue which renders it completely unusable, unless you're careful with your tapping. A new level of skeuomorphism, I guess, non-physical buttons that get stuck.

  The AC to backspace change really screwed me up and I'm back on a third party calculator. It's a speed bump that feels like hitting a brick wall every time!
