I am trying the following:
#+TBLFM: @-I$4..@+I$4 = if("$3" == "nan", string(""), $3 - $2) ; %.1f
and:
#+TBLFM: @-I$4..@+I$4 = if("$3" == "", string(""), $3 - $2) ; %.1f
But in both case the fourth field is filled when the third field is empty.
What am I doing wrong?
I am using version 8.2.1.

The following does work:
#+TBLFM: @-I$4..@+I$4 = if($3 - $2 == -$2, string(""), $3 - $2) ;
But is not what is described.
I removed
%.1f
because that displays an empty string as 0.0.
Is it possible to use %.1f without making an empty field displayed as 0.0?

I suggest that I will improve the TBLFM example about "nan" in the
manual like this:
`if("$1" == "nan" || "$2" == "nan", string(""), $1 + $2); E f-1'
Sum of the first two columns. When at least one of the input
fields is empty the Org table result field is set to empty. `E'
is required to leave empty fields without conversion to 0. `f-1'
is an optional Calc format string similar to `%.1f' but leaves
empty results empty.
Would this have answered all your questions?
