Usage notes

edit

A decimal point itself is pronounced as てん (ten, literally dot). For example, 9.58 is pronounced as きゅうてんごーはち (kyū ten gō hachi, literally nine point five eight) and 19.19 is pronounced as じゅうきゅうてんいちきゅう (jū-kyū ten ichi kyū, literally ten-nine point one nine).

きゅう (kyū)
てん (ten)
きゅう (kyū)
はち (hachi)

In vertical writing, [[.]] is replaced with . For example, 9.98 is written as 9・98 in vertical writhing. However its pronunciation does not change.

There is some exception. てん (ten, literally dot) is sometimes replaced with コンマ (konma, literally comma), especially when integer part is zero. For example, 0.31 is normally pronounced as れいてんさんいち (rei ten san ichi, literally zero point three one) or exceptionally pronounced as れいコンマさんいち (rei konma san ichi, literally zero comma three one). In this case, integer part is sometimes omitted to pronounce. 0.3 can be read as コンマさん (konma san, literally comma three).
