/**	@file	dk3md.h	Support for the long double type.
Some systems provide a "long double" type, other systems don't.
On some systems the long double type is defined but is the same
as simple double.

The dk3md module makes the using long double easier, you can write

@code
dk3_double_t a, b;
... set a and b ...
a = a + b;
b = dk3md_sin(a);
@endcode
instead of
@code
#if HAVE_LONG_DOUBLE && (SIZEOF_LONG_DOUBLE > SIZEOF_DOUBLE)
long double a, b;
... set a and b ...
a = a + b;
b = sinl(a);
#else
double a, b;
... set a and b ...
a = a + b;
b = sin(a);
#endif
@endcode
