This is not related to Octave API, you are reading and writing doubles 
formatting 
them as integers with "%d":

http://www.cplusplus.com/reference/cstdio/printf/

BTW, why are you using C-style IO rather than C++?

http://www.cplusplus.com/reference/istream/istream/operator%3E%3E/
http://www.cplusplus.com/reference/ostream/ostream/operator%3C%3C/

That is a matter of taste, but I find that iostream is usually much more 
convenient ...
