  LIB$CVT_DX_DX, Text, and X Floating? 
 The Question is:
 
I am trying to convert floating-point numbers into text and vice versa.
 
I have managed to get this to work for all but one floating-point type, the
 X_FLOAT, which is the problem.
 
I am using LIB$CVT_DX_DX to convert an FP descriptor into a text one and vice
 versa. The VMS documentation is clear as to what to do for all types but the
 X_FLOAT. Indeed, LIB$CVT_DX_DX rejects DSC$K_DTYPE_FX as being an unknown type.
 
The question is, how do I carry out a conversion of X_FLOAT to text and vice
 versa? I do not want to lose precision by converting the X_FLOAT to a T_FLOAT
 first if I can possibly avoid it.
 
 The Answer is :
 
  Your version of OpenVMS Alpha does not have IEEE X-Float floating
  point conversions.
 
  This support is under consideration for a future OpenVMS release.
 
  In the interim, you will have to convert the value directly.
 
  Other topics related to floating point -- in addition to what is
  available in the AskQ support database and in the OpenVMS and C
  manuals and in example resources cited in the OpenVMS FAQ -- include

  (8739), (8846), (9091), (9436) and likely other topics.
