decimal_to_floating,  decimal_to_single,  decimal_to_double,
     decimal_to_extended,  decimal_to_quadruple - convert decimal
     record to floating-point value


     #include <floatingpoint.h>

     void   decimal_to_single(single   *px,   decimal_mode   *pm,
     decimal_record *pd, fp_exception_field_type *ps);

     void   decimal_to_double(double   *px,   decimal_mode   *pm,
     decimal_record *pd, fp_exception_field_type *ps);

     void  decimal_to_extended(extended  *px,  decimal_mode  *pm,
     decimal_record *pd, fp_exception_field_type *ps);

     void decimal_to_quadruple(quadruple *px,  decimal_mode  *pm,
     decimal_record *pd, fp_exception_field_type *ps);


     The  decimal_to_floating()  functions  convert  the  decimal
     record  at *pd into a floating-point value at *px, observing
     the modes specified in *pm and setting exceptions in *ps. If
     there are no IEEE exceptions, *ps will be zero.

     pd->sign and pd->fpclass are always taken into account.  pd-
     >exponent,  pd->ds and pd->ndigits are used when pd->fpclass
     is fp_normal or fp_subnormal. In  these  cases  pd->ds  must
     contain  one or more ascii digits followed by a NULL and pd-
     >ndigits is assumed to be the length of the  string  pd->ds.
     Notice  that for efficiency reasons, the assumption that pd-
     >ndigits == strlen(pd->ds) is NEVER verified.

     On output, *px is set to a correctly  rounded  approximation


     Thus if pd->exponent == -2 and pd->ds ==  "1234",  *px  will
     get  12.34  rounded to storage precision. pd->ds cannot have
     more than DECIMAL_STRING_LENGTH-1 significant digits because
     one  character  is used to terminate the string with a NULL.
     If pd->more != 0 on input  then  additional  nonzero  digits
     follow  those  in  pd->ds;  fp_inexact is set accordingly on
     output in *ps.

     *px is correctly rounded  according  to  the  IEEE  rounding
     modes   in   pm->rd.  *ps  is  set  to  contain  fp_inexact,
     fp_underflow, or fp_overflow if any of these arise.

     pm->df and pm->ndigits are not used.
