π can stand for a variety of things in maths, but is 3.14159... the only constant it's conventionally used for?

@christianp I've seen applications where subscripts were added to \(\pi\) to denote a constant not quite related to the circle; would that count?

@tpfto I think not, for the specific thing I'm working on. But out of curiosity, what values did the subscripted π take?

@christianp http://www.m-hikari.com/ams/ams-2012/ams-121-124-2012/elgindiAMS121-124-2012.pdf was one of the papers I had in mind, where for a real \(p\), there is an associated version of \(\sin\), \(\cos\), and \(\pi\). (The usual ones correspond to \(p=2\).)

@christianp ...and now I just remembered that someone thought to look at a \(q\)-analog of \(\pi\): https://mathworld.wolfram.com/q-Pi.html

@tpfto @christianp I've seen this in the context of Lᵖ-space circles and the ratio C/D thereof.

@bmreiniger @tpfto yes, that's where I've seen it. The diagrams in @tpfto's linked paper led me to think it was the same sort of thing, but I think they generalised it even further than that, at first glance
