    I get: (exp(Pi*sqrt(4*41-1))-744)^(1/3) = 640319.9999999999999999999999993903173522456062 Actually I did: $ bc -l scale=40 p=3.1415926535897932384626433

      I get:

      (exp(Pi*sqrt(4*41-1))-744)^(1/3) =
      640319.9999999999999999999999993903173522456062

      Actually I did:
      $ bc -l
      scale=40
      p=3.1415926535897932384626433
      s=sqrt(163)
      w=e(p*s)-744
      e(l(w)/3)

      when I use "bc -l" on Unix.

      WOW! I count 24 9's after the decimal point. Is 744 a fudge factor?

      I, for one, would be interested in how this applies to Euler's formula.
      Yes, I did look at the page referred to by David, but it was beyond me.
      I'll look at Ribenboim tonight.

      PS: Test you favorite 64-bit calculator with

        IIRC, this number was mentioned in Scientific American, Mathematical Games
        column, April 1976 in a April Fool's hoax. It must be in one of Martin
        Gardner's books too. But that doesn't have much info about it.
