As an example, I want to write the decimal number 3.78 Is it common to write it as 三.七八 with Kanji? What about 点? Is 三点七八 being used?

1 Answer 1


First note that, when the text is written horizontally, kanji numerals won't be used normally.

Regardless of text directions, it seems the norm is to use ・(なかぐろ) .

This page quotes 「記者ハンドブック」(第8版:1997年共同通信社刊)



So 3.78 will be written 三・七八.
