// ISO/IEC TR 24733 doesn't say explicitly that the conversion from a

// decimal floating-point type to a generic float type is prohibited but

// it implies that in section 4.3 when it says "In C, objects of decimal

// floating-oint type can be converted to generic floating-point type by

// means of an explicit cast.  In C++ this is not possible."  Check that

// attempt to do a cast are flagged as errors.
