The one most likely to be non-IEEE is ARM, which has a middle-endian representation; to make it explicit, it's the middle case here (FLOAT_WORDS_BIGENDIAN but not WORDS_BIGENDIAN): #if WORDS_BIGENDIAN unsigned int negative:1; unsigned int exponent:11; unsigned int mantissa0:20; unsigned int mantissa1:32; #else #if FLOAT_WORDS_BIGENDIAN unsigned int mantissa0:20; unsigned int exponent:11; unsigned int negative:1; unsigned int mantissa1:32; #else unsigned int mantissa1:32; unsigned int mantissa0:20; unsigned int exponent:11; unsigned int negative:1; #endif #endif Does anyone know if that makes it non-IEEE?
