== Approximation ==
45/44 is extremely close to a single step of [[31edo]], and is represented consistently there as well. When one uses 45/44 as an interval in its own right, it has properties akin to a sort of [[chroma]], and it differs from [[8192/8019]], the Alpharabian inframinor second, by the [[schisma]].
 
== Temperaments ==
[[File:Oceania's cake.jpg|thumb|Ocean's cake]]
 
45/44 is also known as the '''cake comma''', from when [[Ocean Stegosaurus Tardigrade]] was baking a cake and misread flour and sugar measurements on his scale, leading to the inclusion of 11/9 times the amount suggested in his recipe. To compensate, he writes "I increased all the other ingredients by a neutral third, except the eggs, which I increased by a major third because I couldn't be bothered to measure out eight ninths of an egg." We see here the equating of 11/9 with 5/4, leading to the [[tempering out]] of 45/44. The cake turned out fine but slightly burnt on the top.
 
This temperament is the [[Catalog of rank-4 temperaments #Cake (45/44)|cake temperament]], [[support]]ed by the [[patent val]]s for [[12edo|12-]], [[19edo|19-]], and [[26edo|26-tone equal temperament]].
 
== Notation ==
=== Sagittal notation ===
In the [[Sagittal]] system, the downward version of this comma (possibly tempered) is represented by the sagittal {{sagittal | (!( }} and is called the '''11/5 small diesis''', or '''11/5S''' for short, because the simplest interval it notates is 11/5 (equiv. 11/10), as for example in C–D{{nbhsp}}{{sagittal | (!( }}. The upward version is called '''5/11S''' or '''11/5S up''' and is represented by {{sagittal| (|( }}.
