原題與已知條件

exact residual、forward error、conditioning與tolerance convention。操作=numerr-affine-residual-forward；明示資料={"approximation":2,"intercept":7,"slope":3}；請依 exact_ordered_tuple_declared_by_interface 回答。

• G001 — exact residual、forward error、conditioning與tolerance convention。操作=numerr-affine-residual-forward；明示資料={"approximation":2,"intercept":7,"slope":3}；請依 exact_ordered_tuple_declared_by_interface 回答。

定義與適用範圍

沿用原題明示的論域、假設與來源 MKO 定義。本題已完成第二對話數理與中英語義覆核，並由原始參數逐題獨立重算模型、答案與每個算術步驟；原題仍為 candidate。
