Thanks very much.. and thanks also for 1000 decimal pi

1. How can I find the near-to-exact value of pi in decimal mode
(the algorithm)?

2. Can eu use a more value than using 8byte floating point but not
using string numbers?

>> In Windows calculator (calc.exe), (scientific mode)
>> if we click on "pi" the display is:
3.1415926535897932384626433832795
>> Then click "-", and select Edit/Copy. then select Edit/Paste.

>> So 3.1415926535897932384626433832795 subtract
>> 3.141592653589793238462643383279 (no "5" in the display).

>> then click "=".

>> I get the result is 5.0288419716939931148196659300057e-31

>> and so on ...

r> The correct answer up to 10e-62 is:
r> 5.0288419716939937510582097494459e-31
r> in comparison to your result:
r> 5.0288419716939931148196659300057e-31

r> See the difference?! So far to accuracy.

r> Have a nice day, Rolf

r> PS:

r> If you want to find it out yourself, here is PI up to about 1000
decimal

r> Here are the first 1000 digits of PI in decimal representation
(but what
