You can also:

1. add the field to your report normally
2. right click it, select "Format Field"
3. Click the Number tab and click Customize
4. In the Decimals formula, enter something like: if {@test} - truncate({@test}) <> 0 then 1 else 0

The formula tests if the field is an int. If so, show 1 decimal place, otherwise show 0. This method has the advantage of not changing the datatype to text which will make totalling and calculating easier.

Create a formula with:

if remainder({database.field},truncate({database.field})) = 0 then
  totext({database.field},0)
else
  totext({database.field},1);

This will however convert the number to text so if you have to do any calculations then just use the original {database.field} in your calculations. This will also round to one decimal place. Not the most elegant!

• Choose "format field" on the field you want to edit
• In "Decimals" field out a Formula

• Type this formula

   if(Int({Field})<>{Field}) 
    then 1 
    else 0
