Quote:DogHandgamerfreak,

Pi IS a real number, but because it is irrational, the decimal expansion of its digits never repeats. For a rational number (that is, a number that is the ratio of two integers), the digits eventually begin to repeat ad infinitum.

Hope this helps!

Yes, but how many repeating digits before you can be sure it’s the end of the number?

Like mentioned/linked previously, there are spans of 12/13 repeating digits.

Quote:gamerfreakGoogle has broken the word record by calculating Pi to 31.4 trillion digits

https://cloud.google.com/blog/products/compute/calculating-31-4-trillion-digits-of-archimedes-constant-on-google-cloud

Google ran like crap that day.

What google really did was have the worlds most resource intensive hogging AD for the google cloud service.

What a waste of the planets energy resources.

I still use "3" more often than any other pi number, in order to estimate the circumference of a tree [tho just as likely to use 1/pi, thus 1/3 , for an estimate of the diameter knowing the approx. circumf.]Quote:TomGOne of the very first values for c/d used in human history was 3. So I vote to celebrate Pi for the entire month.

It's a fallacy to think you are getting a more accurate number by taking pi out to more decimals if you are estimating diameter or circumference to begin with

at the moment I don't remember why I need that sometimes, though curiosity about a nice big tree is it often I think

according to the calculator I usually use, this is an error of 0.0012644892673496615 in excess of actual pi

Quote:JoemanHey, can we celebrate Pi Day all over again on the 22nd of July (22/7)?

Absolutely. You can also celebrate it in January (3.1)

Quote:gamerfreakYes, but how many repeating digits before you can be sure it’s the end of the number?

Use long division to solve 1 ÷ 3 and you'll see you can sometimes be sure after a number repeats one time

I went through a thing, during cocktail hour, but realize now that 3 and one seventh = 22/7

btw some more dead sea scrolls turned up, and there's some Genesis stuff in the new ones about pi that had been lost:

Quote:and then God said "Let the ratio of the circumference of a circle to its diameter equal about 22/7, but actually make it an irrational number, to drive certain types off the deep end"

PS you can diss 22/7 if you want to, but it represents less error than 3.14

error of 0.0015926535897932 [for 3.14] versus 0.0012644892673496 [for 22/7]
