How to Round to Decimal Places in JavaScript?
You need not fret and automatically think that JavaScript is difficult to learn. You can master it. We encourage you to try out the code for yourself and notice how much smaller the program's overall file size is versus straight-up JavaScript code that does not use Math. round() or Math. floor().

//There are meny ways of rounding...
Math.floor(5.5) //Answer 5, it alwas rounds down.
Math.round(5.5) //Answer 6, it simpily rounds to the closest whole number.
Math.ceil(5.5) //Answer 6, it alwas rounds up.
//You can do more things too...
Math.floor(5.57 * 10) / 10 //Answer 5.5, the number turns into 55.7, Then gets floored (55.0), Then gets divied, (5.5).

function round(num, places) {
num = parseFloat(num);
places = (places ? parseInt(places, 10) : 0)
if (places > 0) {
let length = places;
places = "1";
for (let i = 0; i < length; i++) {
places += "0";
places = parseInt(places, 10);
}
} else {
places = 1;
}
return Math.round((num + Number.EPSILON) * (1 * places)) / (1 * places)
}
round(1.005, 2); // 1.01
round(1.005, "1"); // 1
round("1.23", 1); // 1.2
round("1.436", "2"); // 1.44

// rounds the result to the closest integer
//syntax Math.round(x);
console.log(Math.round(0.9));
// expected output: 1
console.log(Math.round(5.95), Math.round(5.5), Math.round(5.05));
// expected output: 6 6 5
console.log(Math.round(-5.05), Math.round(-5.5), Math.round(-5.95));
// expected output: -5 -5 -6

You should note that this method works only when you have a number that is an integer divided by another integer.
