QDataStream stores your content in a portable binary format. Specifying the floating point precision makes it clear that real numbers, be them represented in floats or doubles in C++, are stored as floats or doubles in file. If you want to store a float as a float, and then a double as a double, you need to change the precision of QDataStream in between calls. Plus, the code that reads the file must match the code that wrote the stream.
