Is it possible to use FSCANF or SSCANF to read ASCII data that contains NaNs and Infs?

I would like to know if it is possible to use FSCANF or SSCANF to read ASCII data that contains a NaN's or an Inf.

On some machines, it is possible to read data that contain NaN's and Inf's.

The following machines can read NaN's and Inf's:

Macintosh

SunOS 

Solaris 

IBM RS/6000

DEC Alpha/OSF (fscanf only)

The following machines cannot read NaN's and Inf's:

MS-Windows

HP 

SGI

If your machine cannot read NaN's and Inf's then you will have to read in the file one line at a time and convert it to its numeric values. For example:

f = fopen('file.dat', 'rt');

tmp = fgetl(f);

fclose(f);
