Converts a 32-bit float from the host’s native byte order to a platform-independent format. func CFSwapInt16(UInt16) -> UInt16 Swaps the bytes of a 16-bit integer. func CFSwapInt16BigToHost(UInt16) -> UInt16 Converts a 16-bit integer from big-endian format to the host’s nat...
嵌入式软件开发时,大小端字节序和Byte Swap是很常见的事情,许多工具软件诸如Modbus Poll和Modbus Slave都提供了数值(short,unsigned short,int, unsigned int,long long,unsigned long long,float,double等数值)的4种表示方式:Big-endian(大端)、Little-endian(小端)、Big-endian byte swap、Little-endian byte swap...
