decimal_checked API

DecimalChecked is a closed IEEE decimal pipeline. It keeps one immutable DecimalContext, the current defined Decimal, flags raised by the latest operation, and flags accumulated across all operations.

Construction And Observation

parse and the from_* constructors apply the supplied context after forcing its IEEE profile. value, context, raised, and flags expose each state component; outcome returns the value with accumulated flags. clear_flags starts a new observation window without changing the value or context.

Contextual Operations

Every arithmetic method delegates to the matching decimal contextual operation and combines its flags. Binary methods take a plain Decimal, so two independently accumulated contexts are never merged implicitly. IEEE NaN and infinity results remain values rather than becoming ArithmeticError.
