//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).var avg=10.55;
console.log(Math.round(avg)); //Prints 11Math.round(3.14159 * 100) / 100 // 3.14
3.14159.toFixed(2); // 3.14 returns a string
parseFloat(3.14159.toFixed(2)); // 3.14 returns a number
// There are many ways of rounding...
Math.ceil(5.5) // Answer 6, rounds up.
Math.round(5.5) // Answer 6, rounds to the closest whole number.
Math.floor(5.5) // Answer 5, rounds down.
// ceil is short for ceiling(up), floor is down...var myNumber = 33.55;
var output = Math.round(myNumber);
console.log(output)
//Output: 34;// 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
