    You might like to reconsider that statement about pi, Equi.

    hmm.. isn't pi = 3.14?
  5. Jan 15, 2009 #4
    Pi is an irrational number, 3.14 is very much rational. What do you think?

    No, pi is "transcendental"; one cannot write it as a terminating decimal nor a recurring one for that matter. Here are the first one million digits: http://www.eveandersson.com/pi/digits/1000000

    Pi is approximately 3.14 (to two decimal places), not equal to.
