This is about scientific notation, and how Gnome Calculator still doesn’t do it correctly.<\/strong><\/p>\n So I was checking a simple calculation<\/a> today, and couldn’t find a proper calculator<\/a>, so I reached for gnome-calculator<\/a> on the desktop. That was a mistake.<\/p>\n It seems to think that<\/p>\n comes to<\/p>\n which is not correct. It would, if I’d\u00c2\u00a0 typed it as:<\/p>\n You can only get the right answer (1333.333\u00e2\u20ac\u00a6) if you type<\/p>\n so it’s clear that gnome-calculator isn’t apply the right exponentiation operator precedence when you hit \u00e2\u20ac\u02dc\u00c3\u201410y<\/em><\/sup>\u00e2\u20ac\u2122. It would have been so much better if gnome-calculator supported ‘E’ scientific notation (1.333E21 for 1.333\u00c3\u201410\u00c2\u00b2\u00c2\u00b9).<\/p>\n A bug<\/a> is filed, but I don’t think I trust it any more. 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?<\/p>\n Update, 2021<\/strong>: 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<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":" This is about scientific notation, and how Gnome Calculator still doesn’t do it correctly.
