No, I always use gdb :)

It also has a persistent history, variables, functions, base conversion, etc. I guess it doesn't have unit conversion or a math library, but it's a great programmers calculator.

I love the JS console for this sort of thing. It has autocomplete for math functions, lists and variables. And I know (and have muscle memory for) the JS math library already.

The best part is its available anywhere, on any computer, in any web browser without installing anything.

Seeing as others in this thread use the bog standard console - and I’ve seen other developers do exactly what you’re referencing - it seems such console usage isn’t unique to you at the very least.
