Math.random()-

• This is simply a function that generates a random floating-point number when it is been called.

• So by default, its value ranges from (0 - 0.99999.....) it never reaches to one.

And the most unique thing is that it generates different value every single time . There is no pattern of the values generated.

Math.floor()-

This function rounds down a number to the next smallest integer or in other words, we can say that with the help of this function, it converts the float numbers into integers.

Example-

var n=Math.random();

console.log(n);

OUTPUT - 0.954137, 0.25469, 0.6547135 etc.

Example-

var n=Math.random();

n=n*6; // while multiplying by 6 it will now produce random (0.1256 - 5.14236)

console.log(n);

OUTPUT - 1.4252, 4.31456, 5.34863 etc

Example-

var n=Math.random();

n=n*6;

n=Math.floor(n)+1; //adding 1 will give numbers from (1 - 6)

console.log(n);

OUTPUT - 1, 6, 4, 5, 2, 3 etc
