toFixed() Method – How to Fix the Number of Decimal Digits

toFixed() specifies the number of digits browsers should show after a number’s decimal point.

Syntax of the toFixed() Method

toFixed() accepts only one optional argument. Here is the syntax:

number.toFixed(totalFractionDigits);

The totalFractionDigits argument specifies the number of digits browsers should show after the number’s decimal point. If omitted, browsers will use 0—which means it will add no digits after the decimal point.

Examples of the toFixed() Method

Below are examples of the toFixed() method.
