JavaScript Math round() Method Last Updated : 16 Sep, 2024 Comments Improve Suggest changes Like Article Like Report The JavaScript Math.round() method rounds a number to the nearest integer. It rounds up for decimal values of 0.5 and higher, and down otherwise.Syntax:Math.round(value);Parameters:value: It is the number that you want to round off.Return Value:The Math.round() method returns the value of the given number rounded to the nearest integer.Example 1: To round off a number to its nearest integer. javascript let round =Math.round(-5.8); console.log("Number after rounding : " + round); OutputNumber after rounding : -6 Example 2: The Math.round() method itself rounds off a negative number when passed as a parameter to it. To round off a negative number to its nearest integer, the Math.round() method should be implemented in the following way: javascript let round =Math.round(-5.8); console.log("Number after rounding : " + round); OutputNumber after rounding : -6 Example 3: The below program shows the result of the Math.round() method when the parameter has ".5" in decimal. javascript let round =Math.round(-12.5); console.log("Number after rounding : " + round); let round1 =Math.round(12.51); console.log("Number after rounding : " + round1); OutputNumber after rounding : -12 Number after rounding : 13 We have a complete list of Javascript Math Objects methods, to check those please go through this Javascript Math Object Complete reference article.Supported BrowsersGoogle ChromeEdge FirefoxOperaSafari Comment More infoAdvertise with us Next Article JavaScript Math round() Method S Shubrodeep Banerjee Follow Improve Article Tags : Misc Competitive Programming JavaScript Web Technologies DSA javascript-math JavaScript-Methods +3 More Practice Tags : Misc Similar Reads JavaScript Math E Property The Math.E is a property in JavaScript that simply returns the value of Euler's Number, which is nothing but just has a base of the natural logarithm.
