Example 3: math.round in javascript

let xo =7.45;
xo = Math.round(xo);
// output = 7;

Example 4: math.round js

// 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
