Lodash is a JavaScript library that works on the top of underscore.js. Lodash helps in working with arrays, strings, objects, numbers, etc.
The _.round() method is used to compute number rounded to precision.
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: Here, const _ = require(‘lodash’) is used to import the lodash library into the file.
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:
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:
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
