C – Serialization of the floating point numbers (floats, doubles)

by

Assuming you’re using mainstream compilers, floating point values in C and C++ obey the IEEE standard and when written in binary form to a file can be recovered in any other platform, provided that you write and read using the same byte endianess. So my suggestion is: pick an endianess of choice, and before writing or after reading, check if that endianess is the same as in the current platform; if not, just swap the bytes.
