The article isn't even using π, but 'pi'. I don't think they strove for rigour and formality.

So, if the article was serving up on a raspberry pi instead of sprinkles on frosting, that would make things more rigourous/formal?

Or per 'simulating pi', what was done to rule out the article being baked & served using a qem rasberry pi?[0]

Huh? Sorry, I'm a bit dumbfounded.

What does the Raspberry Pi have to do with anything here?

Semiotic breakdown:

Ok, jumping into the deep end of the pool, potential semiotic [0] interpretations:

bug screen (Poisson) & computing grid (Fourier).

Permits one to crunch the numbers without eating the sprinkles. aka gets around the 'You can't have your cake and eat it'[1] issues.

symbolically supports the no formalism approach: a) Pi is irrational number. b)Raspberry is stand in for Bronx cheer [2][3].

Perhaps not being able to eat the cake & complete the project is a good idea (less sugar high & more realistic interpretations/results).

Well the subject matter is someone baking a cake for “pi day” - I think colloquial English is probably fine in this context :)
