https://community.intel.com/t5/Software-Archive/IEEE-floating-point-byte-ordering/m-p/896398#M10448 Can anyone confirm that the byte ordering of Intel x86 IEEE floating point binary data is reversed with respect to PowerPC (big endian) data? I have a file containing binary floating point data that was created on an x86 machine, and I need to read it on a PowerPC machine. I'm trying to understand whether the IEEE floating point standard specifies the exact byte ordering, or whether the byte ordering depends upon the processor...<BR /><BR /> Wed, 29 Nov 2006 01:43:17 GMT kencclark 2006-11-29T01:43:17Z https://community.intel.com/t5/Software-Archive/IEEE-floating-point-byte-ordering/m-p/896398#M10448 Can anyone confirm that the byte ordering of Intel x86 IEEE floating point binary data is reversed with respect to PowerPC (big endian) data?

You might want to search the web however. In my short search I found that PowerPC processors are switchable allowing them to be configured as little endian or big endian.
