/// Half-precision floating point type.
/// This class implements an IEEE-conformant half-precision floating point type with the usual arithmetic operators and
/// conversions. It is implicitly convertible to single-precision floating point, which makes artihmetic expressions and
/// functions with mixed-type operands to be of the most precise operand type. Additionally all arithmetic operations
/// (and many mathematical functions) are carried out in single-precision internally. All conversions from single- to
/// half-precision are done using the library's default rounding mode, but temporary results inside chained arithmetic
/// expressions are kept in single-precision as long as possible (while of course still maintaining a strong half-precision type).
///
/// According to the C++98/03 definition, the half type is not a POD type. But according to C++11's less strict and
/// extended definitions it is both a standard layout type and a trivially copyable type (even if not a POD type), which
/// means it can be standard-conformantly copied using raw binary copies. But in this context some more words about the
/// actual size of the type. Although the half is representing an IEEE 16-bit type, it does not neccessarily have to be of
/// exactly 16-bits size. But on any reasonable implementation the actual binary representation of this type will most
/// probably not ivolve any additional "magic" or padding beyond the simple binary representation of the underlying 16-bit
/// IEEE number, even if not strictly guaranteed by the standard. But even then it only has an actual size of 16 bits if
/// your C++ implementation supports an unsigned integer type of exactly 16 bits width. But this should be the case on
/// nearly any reasonable platform.
///
/// So if your C++ implementation is not totally exotic or imposes special alignment requirements, it is a reasonable
/// assumption that the data of a half is just comprised of the 2 bytes of the underlying IEEE representation.
