How can I read data file with maximum float point available line by line?

Question

Hello, I have two routines reading different data files (txt). First data file is like that:

2.281000003 2.593500003 2.749750003 3.062250003...

Routine is:

fid = fopen('v2-eq3.txt','r');
atensao=fscanf(fid,'%f');
fclose(fid);

Result:

Why I can't read the original file correctly?

The second data file (txt) is like that:

0141451080390089-0.00224036502008852i
0163497695135516-0.00258954909383903i
0141451080390089-0.00224036502008852i...

Routine is:

fid = fopen ('i2-eq3.txt','r'); 
ii  = 1;
while ~feof(fid)
    acorrente(ii, :) = str2num(fgets(fid));
    ii = ii + 1;
end
fclose(fid);

Result:

01415-0.0022i
0163-0.0026i
0141-0.0022i...

So, what's wrong? Why I can't read the original files correctly? Could someone teach me? Thanks a lot.

At the MATLAB command line, give the command

format long g

then display Result again.
