How to Say "Decimal Point" in Italian

punto

/ˈpun.to/

The Italian word for "decimal point" is punto.

Meaning: the point used in English mathematics (noun)

Which one should you use?

While English uses a decimal point, Italian uses a comma to separate integer and fractional parts of a number.

/ˈpun.to/. The stress is on the first of two syllables.

English speakers often mistakenly use punto for decimals in Italian, but the standard mathematical separator in Italy is the virgola.

Because of the different roles of the symbols, a single number like '1.234' could be interpreted as 'one thousand two hundred thirty-four' in Italy if the dot is used as a thousands separator.
The word punto is used in the phrase punto e virgola, which refers to a semicolon.
The Italian punto is also the word used for a stitch in sewing or embroidery.

Nel numero 3,14159, la virgola è posizionata tra il 3 e il 1.
In the number 3.14159, the comma is located between the 3 and the 1.
