Lodash _.round() Method

Lodash _.round() method is used to compute numbers rounded to precision.

Lodash is a JavaScript library that works on the top of underscore.js. Lodash helps in working with arrays, strings, objects, numbers, etc.

Syntax:

_.round(number, [precision = 0])

Parameters:

This method accepts two parameters as mentioned above and described below:

• number: This parameter holds the number to round.
• [precision = 0]: This parameter holds the precision to round to.

Return Value:

This method returns the rounded number.

Example 1: In this example, the lodash library’s _.round() method is used to round the number 7.56 to the nearest integer, resulting in the output value of 8.

Javascript

// Requiring the lodash library
const _ = require("lodash");

// Use of _.round()
// method
let gfg = _.round(7.56);

// Printing the output
console.log(gfg);

Output:

8

Example 2: In this example, the lodash library’s _.round() method is applied to round the number 9.005 to 2 decimal places, resulting in the output value of 9.01.

Javascript

// Requiring the lodash library
const _ = require("lodash");

// Use of _.round()
// method
let gfg = _.round(9.005, 2);

// Printing the output
console.log(gfg);

Output:

9.01

Example 3: In this example, the lodash library’s _.round() method is utilized to round the number 1980 to the nearest hundred (with -2 decimal places), resulting in the output value of 2000.

Javascript

// Requiring the lodash library
const _ = require("lodash");

// Use of _.round()
// method
let gfg = _.round(1980, -2);

// Printing the output
console.log(gfg);

Output:

2000
