Overflow does not accrue its implied inexact flag · case 05

Overflow does not accrue its implied inexact flag.

Member previewVariant 5 · 3 implementations · 10 checks per implementation

Case contract

Stipulated floating exception environment: apply an operation flag set, accrue sticky flags, select enabled trap by priority invalid/divzero/overflow/underflow/inexact, save prior state and clear only requested flags after reporting the trap. Inputs are valid flag names.

Why this case matters

An offline floating representation model isolates a reproducible arithmetic fault.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.

Boundary fixture	Actual	Expected	Outcome
overflow implies inexact	`[[], ["overflow"], null, ["overflow"]]`	`[[], ["inexact", "overflow"], null, ["inexact", "overflow"]]`	Failed
