First of all Float Option means that you have been allotted a seat and you have accepted the seat but you want a better programme than what you have been allotted so once you are allotted a seat in the further rounds, you will lose the seat which was allotted a seat . So, by clicking on Float Option does not mean you are out of counselling process so do not worry have relax. If any queries feel free to ask. All The Best!!!
