National Pi day should be 14/3 surely, using 3/14 gives some staggeringly wrong answers. Umm, 14 (divided by) 3 is not real close, either, 4.666667 3.14 is obviously what somebody had in mind. That's only an approximation, too, but it is as close as the calendar gets. We've already passed 3-14-1592, about 100 years after Columbus sailed West. Jon |

So does 14/3, but I'll give it credit for being a lot closer than 3/14 14/3 = 4.666... according to the math I learned. 3/14 = 0.214285 Methinks that the math folks would be better off celebrating it on July 22 (22/7, doncha know...) -- Don Bruder - - If your "From:" address isn't on my whitelist, or the subject of the message doesn't contain the exact text "PopperAndShadow" somewhere, any message sent to this address will go in the garbage without my ever knowing it arrived.

National Pi Day
Math folks have been decimal for a very long time.
I doubt anyone my age was ever taught about 22/7 Fyi I'm 26 Don Bruder wrote: In article , "Roger" wrote: "Cliff" wrote in message . ..

National Pi Day
I got grilled early into understanding fractions which is the only
reason i know about 22/7 too many people in my generation cant understand fractions and cant see how it helps to let a fraction stand at time rather than decimalizing everything and letting infinite variables sit all ove the place as it gets punched into a calculator I almost failed a college Statistic course because it was how to make a specific model of calculator do stats when i owned a different model of calc And that was a COLLEGE math course (GO figure that specific how to use a calc math course was my lowest mark in all college all the non bs courses i did great in) funny how i can run the numbers for radio AC theory but apparently fail a stats course that needs me to use a specif model of calc Even here in Canada stuff is getting dumbed down Ijust hope its stuff with liited applications that dont bit people downt he way in the long term.
