How to Write Decimals in English: Understanding the Dot

In English, the period (.) is used to represent the decimal point. This means that when you write a number with a fractional component, you place the period between the whole number part and the decimal part.

For example:

• One and a half is written as '1.5'.
• Pi is approximately '3.14159'.

Using the period as the decimal separator is standard practice in English-language publications and is widely recognized in international contexts.
