Why is real.sizeof == 16 on x86-systems?!?Its the IEEE 754 extended format: 64bit mantissa + 15bit exponent + sign.It should be size 10!I mean, alignment may be different, but why wasting so much memory even in arrays?
Padding.x86 ABI prefers things to be aligned, so on x86 it's 12 bytes, x86_64 16 bytes. In both cases you don't get any extra precision over the 80-bits that x87 gives you.
