//en-IN and using this for use formate as using in india default is as US

//its fuction not property

// console.log(Math.round(4.6)); // for if want value without decimal in upper or lower
//but if we want to give we want upper or lower then we can  use different fuctions
// console.log(Math.ceil(4.2)); //ceil mean top
// console.log(Math.floor(4.9)); //floor mean down

// console.log(Math.random());//math.random will give number always between 0 and 1

// console.log((Math.random()*10)+1) // value can be as 0.05 then we will got 0.87 after multiply 10 but  we can avoid it by do +1 and doing multiply by 10 cause we avoid decimal

// console.log(Math.floor(Math.random()*10)+1) // by using Math.floor we will value after round below

// for get minimum or max strictly in math we can use a formula add min
//as
const min=5
const max=50
