Editing Duodecimal (section)

==={{anchor|Humphrey point}}Base notation===
There are also varying proposals of how to distinguish a duodecimal number from a decimal one. The most common method used in mainstream mathematics sources comparing various number bases uses a subscript "10" or "12", e.g. "{{base|54|12}} = {{base|64|10}}". To avoid ambiguity about the meaning of the subscript 10, the subscripts might be spelled out, "{{base|54|twelve}} = {{base|64|ten}}". In 2015 the Dozenal Society of America adopted the more compact single-letter abbreviation "z" for "do'''z'''enal" and "d" for "'''d'''ecimal", "{{base|54|z}} = {{base|64|d}}".<ref name="Volan 2015">{{Cite journal |last=Volan |first=John |date=July 2015 |title=Base Annotation Schemes |url=http://www.dozenal.org/drupal/sites_bck/default/files/DuodecimalBulletinIssue521.pdf |journal=The Duodecimal Bulletin |volume=62}}</ref>

Other proposed methods include italicizing duodecimal numbers "''54'' = 64", adding a "Humphrey point" (a [[semicolon]] instead of a [[decimal point]]) to duodecimal numbers "54;6 = 64.5", prefixing duodecimal numbers by an asterisk "*54&nbsp;= 64", or some combination of these. The Dozenal Society of Great Britain uses an asterisk prefix for duodecimal whole numbers, and a Humphrey point for other duodecimal numbers.<ref name="Volan 2015" />
