It's occurred to me that I should've probably used the term "exact
decimal" in my comment, so please read it as such. (The general class
of decimals include 3 types of decimals: exact, recurring and
non-recurring. Generally when people use the word decimal they tend
to mean "exact decimals". Apologies for not being clearer.)
