    The . (with no number after it) in "%.f" means format with a precision of 0 (which for floats, means round to the nearest integer). You probably just want “%f”

    See http://www.cplusplus.com/reference/clibrary/cstdio/printf/ for a description of the format specifiers (I gather the NSLog format specifiers are a superset of the printf ones)
