How to group employee experience numbers 11.03, 0.11, 10.00 in pivot table and then it should get the count

[vijavad]

Hi i have a sheet with column Total Experience and all these numbers are as follows. 11.03, 0.1,0.11. So my boss wants to know the count of the members as 0-2 years experience how many members, 2-5 years experience how many members, 5-8 years experience how many members,8-10 years experience how many members and finally how many members with 10+ years of experience. So i tried grouping these experience numbers but it says' Cannot group that selection".
So please help me how to get rid out of this situation.
