WebFor example, ordering the 4 bytes of data that represent 123456.00 in a “B A D C” sequence in known as a “byte swap” . When interpreted as an IEEE 744 floating point data type, the result is quite different: Ordering the same bytes in a “C D A B” sequence is known as a “word swap” .

WebOn CPU architectures where the host byte order is big-endian (such as PowerPC) this will swap the byte order; otherwise it will just perform a memcpy from src to dest.
