Ask HN: Why don't calculators have an "into" button? Or do they?

1 pointsby gushogg-blake9 months ago
Multiplication is the same both ways so it doesn&#x27;t matter, but for division I&#x27;m always wanting a button that says (last result) &quot;into&quot; x. Basically division with the two sides swapped.<p>Instead you have to type x, divide button, then type out the last result. Am I missing something?

I used to use one of these<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;HP_48_series" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;HP_48_series</a><p>where you kept values on the stack and could reverse the values with the SWAP key. I currently have a<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;HP_Prime" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;HP_Prime</a><p>which I use in Algebraic mode instead of RPN.

Does your calculator have a reciprocal button? That’d get you to the desired result with only one extra keystroke.
