Any math wiz?(irrational numbers)

[triptoe]

hey i am just curious... how would i generate formula's for irrational numbers? Like i know pi is an irrational number. but is there a list of irrational number formulas somewhere? Can i just multiply pi times different numbers and get diff irrational numbers?

also how do i get pi to print out up to 80 thousand digits?

my pi has a preset width

thanks!

You can calculate Pi to any precision, but you are limited by your computers processor.

For Pi, you would find a formula that describes it, and solve the formula.

You could look up Euler's Constant, for another commonly used irrational number.

Solving formulas isn't helpful as long as you're limited by your datatype precision... you need to look at algorithms for computing arbitrary digits of pi, like here (http://en.wikipedia.org/wiki/Computing_%CF%80) at "digit extraction methods"... also, google for "computing pi to arbitrary precision" or something like that.

You cannot: set of

(Rational numbers are countable)

> Can i just multiply pi times different numbers and get diff irrational numbers?

Yes, but the pi you get as constant is **not** full pi but it's approximation :-)

You need to make program to calculate http://en.wikipedia.org/wiki/Pi . It would take long time :-)

For the record, I would **not** recommend doing it in Python :-) : http://en.wikipedia.org/wiki/Pi#Numerical_approximations

i dont know if you wanted to write a program yourself, but in the repositories there is a program called pi that can calculate pi to different precisions. you might have to enable the backports to download and install it.
