Hex Editor - Binary File Editing Software for Windows
In computing, two basic number representation schemes are used: Little-Endian and Big-Endian. In little-endian scheme, multi-byte values are stored starting from least significant byte to most, and vice-versa in big-endian scheme.
For example, the double word value 0x12345678 will be stored by little-endian computer as:
78 56 34 12
And by big-endian computer as:
12 34 56 78
x86 and x64 processors use little-endian encoding, while some other processors from Motorolla® and IBM® use big-endian encoding.
To change a byte order for the opened window, use the commands available in the View » Byte Order menu. By default, the Ctrl+E key combination is bound to the View » Byte Order » Little-Endian command, while the Ctrl+Shift+E key combination is bound to the View » Byte Order » Big-Endian command.
Floating-point standard (IEEE 754) does not define exact encoding of floating-point data types on little-endian and big-endian computers. According to the standard, encoding should not be affected by the change of byte order, although, floating-point type's bytes are actually swapped on several big-endian platforms.
Hex Editor Neo supports scenarios, where floating-point types are not affected by big-endian byte order, and where floating-point types are affected by the byte order change. The "Byte order change affects floating-point types" option on the General Settings page controls this. This option is ON by default.
