NAME

       bson_decimal128_t - bson_decimal128_t

       BSON Decimal128 Abstraction

SYNOPSIS

          #include <bson/bson.h>

          #define BSON_DECIMAL128_STRING 43
          #define BSON_DECIMAL128_INF "Infinity"
          #define BSON_DECIMAL128_NAN "NaN"

          typedef struct {
          #if BSON_BYTE_ORDER == BSON_LITTLE_ENDIAN
             uint64_t low;
             uint64_t high;
          #elif BSON_BYTE_ORDER == BSON_BIG_ENDIAN
             uint64_t high;
             uint64_t low;
          #endif
          } bson_decimal128_t;

DESCRIPTION

       The  bson_decimal128_t  structure  represents  the IEEE-754 Decimal128 data type. The type
       bson_decimal128_t is an aggregate that contains two uint64_ts, named  high  and  low.  The
       declaration  and  layout  order  between  them  depends  on the endian order of the target
       platform: low will always correspond to the low-order bits of the Decimal128 object, while
       high  corresponds  to  the  high-order  bits.  The  bson_decimal128_t always has a size of
       sixteen (16), and can be bit-cast to/from a _Decimal128.

EXAMPLE

          #include <bson/bson.h>
          #include <stdio.h>

          int
          main (int argc, char *argv[])
          {
             char string[BSON_DECIMAL128_STRING];
             bson_decimal128_t decimal128;

             bson_decimal128_from_string ("100.00", &decimal128);
             bson_decimal128_to_string (&decimal128, string);
             printf ("Decimal128 value: %s\n", string);

             return 0;
          }
