/// This library does not provide support for decimal arithmetic, but
/// it does provide access to the byte representation of decimal
/// values. You can pass these values uninterpreted via AMQP, or you
/// can use a library that supports IEEE 754-2008 and make a byte-wise
/// copy between the real decimal values and `proton::decimal` values.
