-// * Spellout rules for Japanese. In Japanese, there really isn't any
-// * distinction between a number written out in digits and a number
-// * written out in words: the ideographic characters are both digits
-// * and words. This rule set provides two variants: %traditional
-// * uses the traditional CJK numerals (which are also used in China
-// * and Korea). %financial uses alternate ideographs for many numbers
-// * that are harder to alter than the traditional numerals (one could
-// * fairly easily change a one to
-// * a three just by adding two strokes, for example). This is also done in
-// * the other countries using Chinese idographs, but different ideographs
-// * are used in those places.

- // Can someone supply me with the right fraud-proof ideographs for
- // Simplified and Traditional Chinese, and for Korean? Can someone
- // supply me with information on negatives and decimals?

+ // In Japanese, there really isn't any distinction between a number written
+ // out in digits and a number written out in words. The kanji are both
+ // digits and words. This rule set provides two variants:
+ //
+ // %traditional
+ // Traditional CJK numerals for everyday usage.
+ //
+ // %financial
+ // Alternate numerals that are harder to alter than the traditional
+ // numerals to prevent fraud (e.g. changing a traditional one to a
+ // three by adding two strokes). Additionally, items that are usually
+ // dropped or shortened in the traditional form are supplied in full
+ // (e.g. 128 is 1 x 100, 2 x 10, 8 instead of just 100, 2 x 10, 8).
+ //
+ // Note that the Japanese spell out rules, although similar, are different
+ // to those for Chinese. For instance, Japanese omits powers of ten which
+ // are zero, however in Chinese they are included.
