PV collects calculators!

Me too; I love spreadsheets as much as I love great custom knives and really enjoy deconstructing other's work. I learn a lot every time I see a spreadsheet from someone new. It's great.
Switched's calculator inspired me to drag my own fallow job out of the dustbin and fix it. I had a very embarrassing math error in mine and pulled it from circulation a while back. But yesterday I was inspired to fix it and you know, the correction was so simple it was embarrassing. I'd done the work the hardest possible way (which is my standard approach,

) That is okay except when it's also wrong. And such was sure the case.
Anyway, not to play any kind of game but I'd be happy to post it here too if anyone is interested. It takes a different approach and isn't as ammenable to doing things 'your way' as Dan's and Switched are (you do things
my way in my calculator!) but it works and is easy to use. I just don't want to put it out there and have that be taken wrong. Please don't even take the suggestion wrong. PV's calculator collection is what got me going.

I collect calculators too, and use em all for what I think they're best at.
Oh - one other thing. I made my calculator before I even knew anyone else had made one, or I'm sure I would never have bothered. That's what happens when you work in such a vacuum, and I'm sure what contributed to my original math error.
