in reply to Constants you cannot help but remember

Here's what popped out while I was waiting for the tea to brew:
• 1440 -- number of minutes in 24 hours
• 65536 -- 2^16
• 256 -- 2^8
• 1024 -- 2^10
• 1.41459(?) It's been a while since I needed to do geometrical transformations.
• 360 degrees = 2pi rad
• Not exactly a numberic constant, but the size of the standard 80 column Holerith Card is the same size of a dollar bill at the turn of the 19th century.
If I dredged a bit, I might be able to come up with some of the interest rate conversion factors I was using when I worked for a bank back in the 80's. But I'd rather not. It's amazing the amount of 'trivia' you remember that is actually important in context. Thank you for something to keep me amused during my Staff 'Meeting' (which starts in 10 minutes.

Are you thinking of 1/Sin(45) = Sqrt(2) = 1.41421?

It seems you have combined

• sqrt(2) = 1.41421
• Pi = 3.14159
two numbers together, to form a new one!

 [Lady_Aleena]: james28909, I use get_data in a subroutine called movies. [Lady_Aleena]: james28909, I put it at the top of my scratchpad, if you want to look at it. [Lady_Aleena]: I remember being pretty proud of that little sub when I wrote it. [james28909]: oh xD
