Should code pass a int, unsigned short, char etc., these macros incur undefined a behavior due to shift into the sign bit. With 32-bit int, (n) & 0xFF) << 24 is UB. With 16 bit unsigned/int, ( (n) & 0xFF) << 24) is UB. Better to use ( ( ( (uint32_t) (n)) & 0xFF) << 24) etc. bonkers intro lyrics https://ajrnapp.com
