.splice() method -is skipping a index - delete & .filter() is not working perfectly - any other method to do this? 

//try it to see index skipping 

let decimalNumber = [ 0, 1, 2, 1.2, 2.22, 5, 7, 8, 3.54, 5.21, 1.27, 6.3, 0.3, 7.77,];

  for (let key in decimalNumber) {
    let a = decimalNumber[key];
    let b = decimalNumber[key].toFixed(0);

    if (a == b) {
      let c = decimalNumber.indexOf(a);
      decimalNumber.splice(c, 1); //try it to see index skipping 
    }
  }
