int
parseDecimal128Exact(
Decimal128* out,
STRING_TYPE const& str);Load into the specified out the decimal floating point number described by the specified str. Return 0 if out is an exact representation of str, a positive value if str is an approximation of str (i.e., str could not be represented exactly), and a negative value if str could not be parsed. The value of out is unspecified if the function returns a negative value. The parameterized STRING_TYPE must be one of bsl::string, std::string, std::pmr::string (if supported), or bslstl::StringRef.
0 if exact, positive if approximate, and negative if unparsable
