importtool ffnumber

We try to use a script in which we use 'ffnumber'. This is a TFloatFormat that has been declared in the System.SysUtils.pas file. When we use our script, we get an error stating that ffnumber is an unknown variable.
Why isn't this imported by the import tool?

Never mind, I found the ap_SysUtils.pas file in the directory of the scripter.
