writing data to a file

Hi , I have to write big integer numbers into a file (in signed decimal format).I am using "fprintf(fid,'%d\n',data)" command.But the number say 262206552555 is written in the file like 2.6221e11 whereas I want it as 262206552555 .If I use '%f' then i get the full number but with trailing zeros .Please tell how I should go about .

Hmm.. I am unable to reproduce your circumstance..

d=262206552555
fid = fopen('new1.txt', 'w');
fprintf(fid,'%d\n',d);
fclose(fid)

Gives me the output in the file as 262206552555 and not as 2.6221e11

I also am suing the same command as yours.Is there any other setting which may affect??

Sujeet, experiment with using

fprintf(fid, '%d\n', round(d));
