ALV Report - edit option

Question

Hi,
         This is BalaNarasimman. i am making one field  as editable field in alv report.
The requirement is that field should have input with  decimal  also. Eg. 2.2.
So   i  am  declaring    data   type as, data:per    type  P DECIMALS 1.
    if i am giving  input as '2',  then system  is converting as  '0.2'.
    if i want to get '2.2',then i  need  to give '22'.  so    How  can i  avoid       such       kind of situation?                                     
           Please give suggestion to me.
