Return the value of the smallest (negative) number representable 
   in a double precision variable. 

   None. 

   The function returns the value of the smallest (negative) number 
   that can be represented in a double precision variable. 

   None. 

   The function returns the value of the smallest (negative) number 
   that can be represented in a double precision variable. 

   This value varies from machine to machine.  Usually, the value is 
   defined as the negative of the macro DBL_MAX from the ANSI standard
   header file float.h.  According to the ANSI standard, DBL_MAX must be 
   at least

      1.E+37 

   Therefore dpmin_c usually returns a value less than or equal to 

     -1.E+37

   Exceptional systems would be those where DBL_MAX cannot be negated.
   Currently no such systems are supported.      

   None. 

   The function always returns a constant value, set by the user 
   prior to compilation. 

   The following code fragments illustrate the use of dpmin_c. 
   Note in the example that the smallest negative number is not assumed
   to be the negative of the largest positive number. 

   1) Initialize a CSPICE "window."

      /.
      The window originally has one interval, from "minus 
      infinity" to "plus infinity". 
      ./

      winsiz    =  2;
      window[0] =  dpmin_c();
      window[1] =  dpmax_c() ;

      scardd_ ( &winsiz, window ); 

   None. 

   Error free. 

   None.
