Detailed Description

template<std::size_t Precision, std::size_t Scale>
class storages::odbc::Decimal< Precision, Scale >

Exact fixed-point SQL DECIMAL/NUMERIC value.

Accepted syntax is [-+]digits for Scale=0 and [-+]digits.Scale-digits otherwise. Exponents, whitespace, NaN and infinities are rejected. Values are canonicalized by removing a leading plus and redundant integer zeroes; negative zero is normalized to positive zero. Exactly Scale fractional digits, including trailing zeroes, are retained. ODBC SQL_NUMERIC_STRUCT limits portable precision to 38 digits.
