significant byte造句

When you cast the integer into a single byte, only the least significant byte (0x00 to 0x7f) will be copied as a hex value to the single-byte array.

Little-endian means that the least significant byte has the lowest address (the word is stored little-end-first).

Big-endian means that the most significant byte has the lowest address (the word is stored big-end-first).

That is to say, on the x86 system, the least-significant byte (the smallest values) are stored in the first byte of ll; on the Power Architecture system, they're stored in the last.

Basically, the first word is the preferred word, and then the other alignments are on the least-significant byte or halfword of that word.
