This is about scientific notation, and how Gnome Calculator still doesn’t do it correctly.
So I was checking a simple calculation today, and couldn’t find a proper calculator, so I reached for gnome-calculator on the desktop. That was a mistake.
It seems to think that
which is not correct. It would, if I’dÂ typed it as:
You can only get the right answer (1333.333â€¦) if you type
so it’s clear that gnome-calculator isn’t apply the right exponentiation operator precedence when you hit â€˜Ã—10yâ€™. It would have been so much better if gnome-calculator supported ‘E’ scientific notation (1.333E21 for 1.333Ã—10Â²Â¹).
A bug is filed, but I don’t think I trust it any more.
I’m looking at having a proper calculator again, or maybe invest in one of the delightful tiny HP clones from SwissMicros.com.
Almost forgot that I had a barely-used HP 49G in the cupboard. It was barely used because the thing eats AAA batteries. Who knew that Dollarama would have a pair of NiMH AAAs for only $2?
Update, 2021: Use galculator instead. It does the right thing, and supports RPN like a calculator should. You don’t need to remember any precedence rules when you have The Truth.
