π Computation

Yesss. You know you love it.

I'm trying to implement this (http://fabrice.bellard.free.fr/pi/pi_n2/pi_n2.html) algorithm (for fun, mostly). I've run into a problem, however... The paper uses "." as an operator. Have any of you ever seen this usage before, or happen to have any clue what it means?

Normally that's the matrix dot operator... I'm lost as to the applicability in this context, however.

It looks like plain multiplication to me.

For what it's worth, the postscript version is a bit more legible.

I think that's a multiplication operator too.

Seriously? Wow, they really buried that sucker on the bottom of the text line, didn't they?

Looking at the PS file, they have other issues with dropped (ie, subscript) characters where they have no business being.

It's probably the worst PS file I've ever seen—Thanks for the help, though.

The volume of a pizza of thickness 'a' and radius 'z' is given by the formula pi*z*z*a.

edit: this almost made it as my new sig this week. Need more tasting testing. ;)

Or, you can compute pi by dividing the circumference of an igloo by the length of the eskimo...

Everyone knows that the circumference of an igloo is eskimo pi.

Normally that's the matrix dot operator... I'm lost as to the applicability in this context, however.

Is it? So it's just matlab where the dot denotes array multiplication?

Could make sense...it is Matrix Laboratory. :)
