Strange formatting of punctuation

I found the following and several other instances of this same formatting error in this article:

BEGIN QUOTE

For example, let

$f(x,y)={\begin{cases}1&{\text{for }}xy\neq 0\\0&{\text{for }}xy=0\end{cases}}$.

END QUOTE

Is that considered a good way to format the punctuation that ends the sentence? I changed it to the following:

For example, let

$f(x,y)={\begin{cases}1&{\text{for }}xy\neq 0,\\0&{\text{for }}xy=0.\end{cases}}$

Do people look at what they've written after they save it? Michael Hardy (talk) 00:42, 25 June 2026 (UTC)
