This gives the false impression that the variables are all related. If they are related, they should probably be encapsulated in some kind of structure. And once you add the comments explaining what the first three variables are and how they should be used, and the comment explaining why pi doesn't have a decimal point, there is no benefit to alignment. If you add another long line, you have to realign the whole list (or leave it looking sloppy). Overall, this kind of alignment is a bad idea.
Congratulations for taking my contrived example way too literally and missing the point entirely.
Not every group of variable assignments warrants a comment for every line, nor is my argument relevant only to static constants, nor is there any reason why aligned assignments should be construed to be related any more than consecutive assignments should be, nor should that stop you from reaping the unarguable improved readability of aligning them anyway.

The true impression. If they're actually unrelated, they're more likely to be in different files outright, than immediately sequential. "Encapsulating" in a struct is pointless/potentially obfuscatory if they're related local temps - but I'll use the same style for initializing structs.

I align those comments too.
