As an expert in linguistics and communication, I can provide a detailed answer to your question. The symbol "a" in English grammar is an indefinite article used before singular nouns that are not specific. It is typically used when referring to something for the first time or when the specific identity of the noun is not important.

Now, let's address the question of whether there is a difference between "a." The period after "a" suggests that it might be the end of a sentence or a decimal point. However, without context, it's challenging to provide a precise answer. If "a." is intended to represent the end of a sentence, it would be incorrect because articles are not punctuated with a period. If it's meant to be a decimal point, then it's a numerical symbol and not an article.
