To: gcc-help@xxxxxxxxxxx Dear GCC, [ 8:2:23 ] Like Woooew ! What is THIS!? I installed Visual Studio Code, & your 32 bit C, Version 9.2.0. I ran : printf("\nOn THIS particular computer, long double is given %d bytes\n", sizeof(long double)); /* The Answer was: 12 bytes. THEN, I updated to C Version 12.2.0 and ran the same code, - ON THE SAME COMPUTER, - but NOW the answer is: 16 bytes ! HOW can this happen if, as I understand it, - this function is supposed to assess a computer’s *hardware* ? I am on Windows 10 btw. — Sergey. С уважением, Sergey Smith sergey-16a5@xxxxxxx
