C++ byte swap
WebFeb 1, 2024 · We refer to the byte holding the smallest position as the Least Significant Byte ( LSbyte) and the bit holding the smallest position as the Least Significant Bit ( LSbit ). A diagram to illustrate that the byte containing the lowest position numbers is the least significant byte. WebApr 5, 2016 · Most compilers, including GCC, Clang, and Visual C++, supply built-in support for byte swapping intrinsics. The Endian library uses these intrinsics when available since they may result in smaller and faster generated code, particularly for optimized builds. Defining the macro BOOST_ENDIAN_NO_INTRINSICS will suppress use of the intrinsics.

Larger groups comprise two or more bytes, for example, a 32-bitword contains four bytes. There are two possible ways a computer could number the individual bytes in a larger group, starting at either end.
Web6,318. Just don't read it as a float, read it into an int, switch the endianness of that if necessary, and then convert it into a float using * (float*)&myInteger. Then if that works - great!
