const num = 56.5467;
const wholeNumberPart = Math.trunc(num);
console.log(wholeNumberPart );

const decimalPart = (num - Math.floor(num)).toFixed(4);   // if we console.log the decimalPart = Math.floor(num);  output : 56, we subtract original number with result.
console.log(decimalPart);

const roundedNum = Math.round(num);
console.log(roundedNum);
