The toFixed() method converts a number to a string. The toFixed() method rounds the string to a specified number of decimals.
Notes:Syntax:
- The
toFixed()method rounds the number if necessary.- If the specified number of digits is greater than the actual number of digits after the decimal point, zeros are added to the end of the string representation.
- If the specified number of digits is less than the actual number of digits after the decimal point, the number is rounded.
number.toFixed( value );Parameters:
It returns a number in the string representation. The number has the exact number of digits after the decimal place as mentioned in the toFixed() method.
Example 1: Using toFixed() method with a parameter 1, displays decimal points to one digit.
JavaScript
let test=213.73145;
console.log(test.toFixed(1));
Example 2: Using toFixed() method without any parameter, If there is no parameter specified in the toFixed() method then it doesn't display any digits after the decimal place.
JavaScript
let test=213.73145;
console.log(test.toFixed());
Example 3: Using toFixed() method with a parameter, If there is a parameter specified in the toFixed() method will return a number represented as a string which will have exactly that number of digits after the decimal place.
JavaScript
let test=213.73145;
console.log(test.toFixed(3));
Example 4: Using toFixed() method where the number is in exponential form. The toFixed() method can be used to convert an exponential number into a string representation with a specific number of digits after the decimal place.
JavaScript
let test=2.13e+15;
