MATLAB: Hold precision number textscan

ascii fileprecisiontextscan

Hellow, i'm using textscan to extract info out of an ascii file. My ascii file has a precision of six numbers after the point. But when i use my program, the numbers convert to a four digit number. my code is:
while (~feof(fid)) % For each block...
      InputText=textscan(fid,'%s',1,'delimiter','\n'); % Read header line
      HeaderLines{Block,1}=InputText{1};
      disp(HeaderLines{Block});
      NumCols= nd;
      FormatString=repmat('%f',1,NumCols);  % Create format string based on parameter
      InputText=textscan(fid,FormatString,'delimiter','slice'); % Read data block
      Data{Block,1}=cell2mat(InputText); % Convert to numerical array from cell
      [NumRows,NumCols]=size(Data{Block});  % Size of table
      disp(cellstr([xlate('Table data size: ') num2str(NumRows) ' x ' num2str(NumCols)]));
      disp(' '); % New line
      Block = Block+1;                            % Increment block index
  end
now when i use InputText=textscan(fid,'%f','delimiter','slice'); the resolution of my matrix isnt right anymore… Thx

The program does not convert to four digits accuracy: you have set Matlab to only display 4 digits by default.
Give the command
format g long
and then display the matrix.
