In this example of x86_64 hex/disassembled code I see:

48B80000000000000000 mov rax, 0x0

    Signed Byte 52
    Unsigned Byte   52
    Signed Short    14388
    Unsigned Short  14388
    Signed Int  943863860
    Unsigned Int    943863860
    Signed Int64    3472328296363079732
    Unsigned Int64  3472328296363079732
    Float   4.630555e-05
    Double  1.39804332763832e-76
    String  48B80000000000000000

which to me appears to have the same functionality as:

48C7C000000000 mov rax, 0x0

    48C7C000000000

    Signed Byte 52
    Unsigned Byte   52
    Signed Short    14388
    Unsigned Short  14388
    Signed Int  927152180
    Unsigned Int    927152180
    Signed Int64    3472328377950746676
    Unsigned Int64  3472328377950746676
    Float   1.163599e-05
    Double  1.39806836023098e-76
    String  48C7C000000000

How is the first example treated differently from the second example?
