Get the Last 2 Digits of a Number in JavaScript

Get the Last 2 Digits of a Number #

To get the last 2 digits of a number:

1. Convert the number to a string.
2. Call the slice() method on the string, passing it -2 as a parameter.
3. The slice method will return the last 2 characters in the string.
4. Convert the string back to a number to get the 2 last digits.

Copied!
const num = 2468;
const last2Str = String(num).slice(-2); // 👉️ '68'
const last2Num = Number(last2Str); // 👉️ 68

The first step is to use the String object to convert the number to a string, so we can use the String.slice method.

The only argument we passed to the slice method is the start index - the index of the first character to be included in the new string.

This is the same as passing string.length - 2 as the start index.

Copied!
const str = 'Hello World';

const last2 = str.slice(-2);
console.log(last2); // 👉️ ld

const last2Again = str.slice(str.length - 2);
console.log(last2Again); // 👉️ ld

The slice method returns a string, so the last step is to convert the string back to a number to get the last 2 digits of the number.
