Actually, it's been playing it for three years (via GamesRadar). That's Pi as in the mathematical constant. The one you probably know as (at least) 3.14 but which goes on, well, forever if you let it.

The Mathematics Behind the Name Interestingly, the ratio of 350 to 111 equals approximately 3.153—remarkably close to Pi (3.142). This mathematical quirk gives the indicator its name and highlights ...

The official solution essentially consists of better power filtering between the hat and the Pi, flattening that power draw. We’re looking forward to getting our hands on this new and improved ...

"Modern maths, physics, engineering and technology could not function without pi." In 2010, Nicholas Sze used Yahoo cloud computing to calculate that the two quadrillionth digit of Pi was zero - a ...
