使用する際の注意点

In the mathematical sense, some languages, such as French, use a term that literally means "body". This denotes a division ring or skew field, not necessarily commutative. If it is clear from context that the quaternions and similar division rings are irrelevant, or that all division rings being considered are finite and therefore fields, this difference is ignored.
