double is 15 (of course depending on the compiler)
Is there anything bigger tha

Answer 1

A long double typically only uses 10 bytes, but due to alignment may actually take up 12 or 16 (depending on the compiler and options) bytes in a structure.

The 10 byte long double provides a 64-bit mantissa; this is very convenient for when you want to store 64 bit integers in floating point without loss of precision.
