However, there is a class of compounds, called non-stoichiometric compounds, that cannot be represented by small integers. Such a formula might be written using decimal fractions, as in Fe 0.95 O, or it might include a variable part represented by a letter, as in Fe 1−x O, where x is normally much less than 1.
