# punctuation after a fraction in math mode

I use to punctuate my equations.

In math mode, when the last "word" is a fraction, I raise the final point using \cdot like in

x = \frac{3}{2} \cdot

so that the "." is at the same height as the fraction bar. So my questions are:

• Is it good practice?
• Is there an equivalent of \cdot for the comma?

Is it good practice? No, in my opinion. – egreg Jan 29 '13 at 12:50
