Math.floor(x);
Don't Tread On Me
Math.floor(x);console.log(Math.floor(5.95));
// expected output: 5
console.log(Math.floor(5.05));
// expected output: 5
console.log(Math.floor(5));
// expected output: 5
console.log(Math.floor(-5.05));
// expected output: -6// 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...// Will round innerHTML value to 2
document.getElementById("myId").innerHTML = Math.floor(2.9);// The Math.floor() function returns the largest integer
// less than or equal to a given number.
console.log(Math.floor(9.8));
// expected output: 10// Math.floor returns the floor of a number
console.log(Math.floor(1.5)); // -> 1
// Using two bitwise not operators '~' you can also get the floor of a number
console.log(~~1.5); // -> 1
