Depends on size constraints.
In the simple case you should convert float to locale-independent
string value (no spaces, no commas separators) then write it.
If the size does matter, you may convert float to corresponding byte
array then write it.
Can I ask a naive question here please: does a binary stream store
endianness anywhere? In other words, is there any indication that
something running on ARM is about to get into trouble by reading
something written by (big-endian) MIPS?
Not that I'm aware of - i would think of it as a stream of bytes.
Endianess is defined by the CPU not by the file.
Should writing binary floating point to a stream note that it's IEEE
format, just in case anybody ever tries to process it on a platform
that supports alternatives?
It would be great if storing floating point could be in IEEE, to have a
standard as reference.
