> IEEE 754 floats don't have different endianess. The standard does not specify endianness [1]. From the standard point of view float is a sequence of bits. But if you memory-map the file and store float on little-endian machine, you get bytes reversed compared to how it is written in the standard. On big-endian machine sign is stored in the first byte, and on little-endian machine sign is stored in the last byte.
