I liked the company standard: selling price is (materials cost) * Pi !!!

If I took that phrase literally (Pi !!!), HP-50G calculates that to be 9.99999999999 E499. Somehow, I think even HP wouldn't be that crazy. Pi !! came to about 7380.55555766, and Pi! comes to 7.1881-ish, or so my HP-34C told me back in the day. That might be closer to the scale that HP was originally thinking of.

When did Pi become a natural number? Factorial is only defined for natural numbers.
