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
This support is under consideration for a future OpenVMS release.
In the interim, you will have to convert the value directly.
