Smartphone killed the calculator star. Some thoughts... and data too

[benbradley]

On the computer, for things not complex enough for LibreOffice spreadsheet, I often use the calculator in MS Windows. You can paste a string of text as a "calculation" to it and then copy-and-paste the result into another document.

I just got the idea to test a few things - this comes out zero:
1/3=*3=-1=
I just went to the Help and found these shortcuts:
S sin
O cos
T tan
I i=Inv
Using those in this text input pasted to the calculator, this gives 9:
9SOTITIOIS
But this:
9SOTITIOIS-9=
gives:
3.3055861301806391104645128745734e-32

But yeah, no doubt the the main calculator market is for the TI model approved/required for USA high school tests.

I'm surprised the 12C is still selling, surely there are apps that do the same thing, or even emulate it?
