       The bson_append_double() function shall append a new element to a bson document of type double.

       • bson: A bson_t.

       • key: An ASCII C string containing the name of the field.

       • key_length: The length of key in bytes, or -1 to determine the length with strlen().

       • value: A double value to append.

       Returns  true  if the operation was applied successfully. The function will fail if appending value grows
       bson larger than INT32_MAX.
