decimal_checked API

DecimalChecked は closed IEEE decimal pipeline です。一つの immutable DecimalContext、current defined Decimal、latest flags、accumulated flags を 保持します。

Construction And Observation

parse と from_* constructor は supplied context を IEEE profile に固定します。 value、context、raised、flags が state component を公開し、outcome は value と accumulated flags を返します。clear_flags は value/context を変えずに 新しい observation window を開始します。

Contextual Operations

各 arithmetic method は対応する decimal contextual operation に委譲し、flags を combine します。Binary method は plain Decimal を取り、独立した context/history を暗黙に merge しません。IEEE NaN/infinity は ArithmeticError ではなく defined result のままです。
