In the IBM model that Aahz is implementing, decimal numbers are not necessarily exact, but (if I understand correctly) you can set a context flag that causes an exception to be raised when the result of an operation on two exact inputs is inexact. This can happen when e.g. a multiplication result exceeds the number of significant digits specified in the context -- then truncation is applied like for binary floats.
