textscan does not output more than 4 decimal digits

I have a comma delimited file and trying to read it using textscan

2011.02.25 8:04 1.38273 1.38309 1.38269 1.38307 71

fid = fopen(fullname);

out = textscan(fid, '%s %s %f %f %f %f %f %f', 'delimiter', ',', 'MultipleDelimsAsOne', 1);

fclose(fid);

However it always outputs me 4 decimal digits not 5 as in file even if i use format like e.g. %7.5f where it sholud output 5 digits

Any idea ??

You're being fooled by the display format. Type in the command line (or access the var from the var editor):

format long
out{:,3}
