/* N1150 5.2: Conversions among decimal floating types and between
5 
   decimal floating types and generic floating types.
6 
   C99 6.3.1.5(3) New.
7 
 
8 
   Perform conversions between DFP types in which the assigned value
9 
   cannot be represented exactly in the result and must be rounded
10 
   correctly according to the current rounding mode.
11 
 
12 
   Normally this would not be part of compiler testing, but conversions
13 
   are currently handled in libgcc via decNumber.  */
