Re: [ferret_users] How to read ASCII data accurately

[Russ Fiedler <russell.fiedler@xxxxxxxx>]

Hi Martin,

Version 6.82 RH6 reads this to full precision so it looks like a
difference between OS or a bug has crept in.

russ-hf% ferret -nojnl
        NOAA/PMEL TMAP
        FERRET v6.82  
        Linux 2.6.32-279.1.1.el6.x86_64 64-bit - 08/03/12
         3-May-13 09:55   
yes? file/var=xx dummy
yes? list/prec=10 xx
             VARIABLE : XX
             FILENAME : dummy
             X        : 1
          734707.0101

There also the /TYPE=r8 qualifier which might work or try specifying the
Fortran format explicitly.
