"The Printing of Mathematics" by Chaundy, Barrett, and Batey, Oxford University Press, 1954, says that mathematics should be punctuated as normal text. For instance, if a formula is at the end of a sentence then it should be followed by a full stop (period).

"Mathematics into Type" by Ellen Swanson, American Mathematical Society, 1999, shows many examples of punctuating math with commas and periods.

I must dig out my copy of Knuth's <i>Mathemtical Typesetting</i> and see what is recommended there, but for myself, while I would happily punctuate inline maths, I would never do the same for display maths unless there were two or more separate fomulæ presented
within a horizontal sequence, e.g.<br>
<br>
$$(a+b)^2 = a^2 + 2ab + b^2 ; (a+b)^3 = a^3 + 3a^2b + 3ab^2 + b^3; ... $$<br>
<br>
Even then I would probably not set a final period.<br>
