2016年9月14日 · This is what the document says, Texas instrument's TMS320C28x C/C++ compiler intrinsics, page 122, int&__byte(int, unsigned int), I guess it is different from PC – …

This is because of implicit conversion. The variables b, c, d are of float type. But the / operator sees two integers it has to divide and hence returns an integer in the result which gets …

2013年1月25日 · Where int8_t and int32_t each have a specified size, int can be any size >= 16 bits. At different times, both 16 bits and 32 bits have been reasonably common (and for a 64 …
