For 10, 100 and 1000, it is common to omit "一" like "十", "百" and "千" instead of "一十", "一十" and "一千" respectively. However, in the case of Daiji, "壱" may be specified.

The numbers after the decimal point are expressed in scaled number system after "・".

Of the above Daiji, Japanese law only stipulates "壱", "弐", "参", and "拾".

In Daiji, digits of "億" (108) or more are not defined, but in DenCode, they are represented by the same digit name as modern Japanese numerals.
