"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.
