Digits printed for value of keywords

[SolarBarn]

I asked exiftool to print the gpsaltitude and it shows 366.8 but I need to know if this is all the digits available.  I know, for example, that when I ask exiftool for the gpslatitude it shows results down to 39.48" (7 foot accuracy) but the actual data in the exif of the file contains 16 decimal digits of data for the seconds (") field according to: Properties --> Details and then look at GPS Altitude entry.  366.8 is only accurate to 10 cm but I am looking for 1 cm accuracy.  Can I change the number of digits printed out when I request exiftool c:\path\to\file\*.jpg -gpsaltitude in order to see if more digits of accuracy are available?

Regards,
Terry.

After searching the forum, I found that I just need to include the -n option.  Then I get values like:
GPS Altitude                    : 359.158
which has mm precision.

Now I am happy.
