Decimal numbers?

Just a simple question really. How do you say decimal numbers in Japanese?

For example 1.5 in English is read one point five. What is the Japanese equivalent?

1.5 = ittengo (it ten go)

The same as with English, we say "ten," the word for "point."

Note that as cc mentioned, 1.5 would be pronounced "ittengo," not simply "ichi-ten-go." If you say "ichi-ten-go," people would understand it alright, though. The change in pronunciation happens with 1 = ichi, and 8 = hachi, as well.

1.5 = itten go
2.5 = ni ten go
3.5 = san ten go
4.5 = yon ten go
5.5 = go ten go
6.5 = roku ten go
7.5 = nana ten go
8.5 = hatten go
9.5 = kyu ten go
