Question

exist any way to store in database a numbers with or without decimal point? The user can store to database numbers like 10 and 10.1 – for storing numbers in MySQL I use data type column decimal, so for this example, in the database will be stored 10.00 and 10.10.

But I will need to store the exact form of number by user – so in this case 0 10 and 10.1.

Is possible to solve it on database level or I have to edit on application level?

make use on case

case format(@number,0)=@number 
  when 1 then format(@number,0) 
  else 
  case format(@number,1)=@number 
    when 1 then format(@number,1) 
    else @number
  end 
end

or if

if (format(@number,0)=@number, format(@number,0),
  if (format(@number,1)=@number, format(@number,1), @number))
