The Chinese "spoken-out" counter styles</h4>
427-
428-
<p>The Chinese "spoken-out" counter styles define a style of numbering roughly
429-
similar to using "one, two, three..." in English. The "financial" variant
430-
is commonly used for writing out quantities of money, as it is somewhat difficult
431-
to modify one "financial" character into another. These styles are defined
432-
for all numbers between -10<sup>16</sup> and 10<sup>16</sup>, exclusive.
433-
There are four Chinese counter styles which are constructed using the same
434-
algorithm, but different sets of characters (given below). The following
435-
algorithm converts decimal digits into Chinese numbers:</p>

The CJK "spoken-out" counter styles</h4>
428+
429+
<p>Chinese, Japanese, and Korean all share almost identical "spoken-out"
430+
counter styles, which are roughly similar to using "one, two, three..." in
431+
English. The Chinese and Japanese styles are defined for all numbers between
432+
-10<sup>16</sup> and 10<sup>16</sup>, exclusive; the Korean styles are
433+
defined for all non-negative numbers less than 10<sup>16</sup>. All of the
434+
styles are defined by almost identical algorithms (specified as a single
435+
algorithm here, with the differences called out when relevant), but use
436+
different sets of characters. The list following the algorithm gives the
437+
name of each counter style using this algorithm, and the individual character
438+
sets used by each style.</p>
439+
440+
<p>For legacy reasons, the counter style ''cjk-ideographic'' must be treated
441+
as an alias for ''trad-chinese-informal''.</p>
