in reply to Re: Golf -- compute PI
in thread Golf -- compute PI

# 23 Characters
use Math::Trig;warn pi;
Why warn, when you can die saving one more character?
# 22 Characters use Math::Trig;die pi;
And, you can shave one more character, if you don't care for that pesky semi-colon at the end.

Oh, never mind. We are not supposed to use trig functions.

    You can get the same result with 20 chars:
    die 3.14159265358979
    I found this trick in Logique, informatique et paradoxes, publisher Belin (Pour la Science), page 67, it was about the shorter program to get (not compute) pi with n digits.

[Your Mother]: They would think so.
[jdporter]: ok, I need a recipe for piping lines "through" an external program which is itself a filter
[jdporter]: without using a tmp file
[1nickt]: tobyink perl -MTypes::Standard= is_Int -Mstrict -wE 'say 1 if is_Int 1.0'
[jdporter]: so that I can use the existing expand unix util. Otherwise, I'll probably use Text::Tabs.
[1nickt]: pryrt I guess I don;t really care if user 42 logs on as 42.0 ... more of an academic question at this point.
[LanX]: jdporter: open PIPE,'-|' ?
[LanX]: oh you want the result line by line?
[jdporter]: ok, LanX, then what?
