[[Interval size unit|Various units have been used for the span of an interval]]. Typically [[cents]] are used, which can be thought of as the logarithm taken to the base <math>2^{1/1200}</math>. However, in mathematical situations it is often useful to work with the log base 2, meaning units of octaves, or even simply in the natural logarithm of base e, meaning units of "[[Wikipedia:Neper|nepers]]". [[Martin Gough]] introduced the unit of a "dineper" in his work on [[Logarithmic approximants]]. For a units analysis of interval size, see [[Dave Keenan & Douglas Blumeyer's guide to RTT/Units analysis#Size of JI interval]] and the following section for [[Dave Keenan & Douglas Blumeyer's guide to RTT/Units analysis#Size of tempered interval|the size of a tempered interval]]. | [[Interval size unit|Various units have been used for the span of an interval]].
