ddeeccvvaaxx_dd() -- General Function (libc)

Convert a double from IEEE to DECVAX format
iinntt
ddeeccvvaaxx_dd(_d_d_p, _i_d_p)
ddoouubbllee *_d_d_p, *_i_d_p;

ddeeccvvaaxx_dd() converts a ddoouubbllee from IEEE format to DECVAX format.  _i_d_p points
to the IEEE-format ddoouubbllee to convert.   _d_d_p points to a destination for the
converted  DECVAX  value;  _d_d_p   may  be  identical  to  _i_d_p  for  in-place
conversion.

ddeeccvvaaxx_dd() returns zero on success, -1 on underflow, or one on overflow.

For  a  description  of the  IEEE  and  DECVAX  formats for  floating-point
numbers, see the Lexicon article for ffllooaatt.
