Is there anything bigger tha

Answer 1

C++ has long double, but there is no guarantee that it's any more precise than a plain double. On an x86 platform, usually double is 64 bits, and long double is either 64 or 80 bits (which gives you 19 significant figures, if I remember right).

Your mileage may vary, especially if you're not on x86.
