Case contract

Pitching line aggregation. outings rows are [innings_pitched, earned_runs] where innings pitched use baseball notation "6.2" = 6 innings and 2 outs (the digit after the point is 0-2; otherwise return "invalid ip <text>"). Sum outs exactly. ERA = innings_per_game * earned runs / innings, rounded half up to two decimals. Return [total innings "I.O", ERA string]; with zero outs ERA is "INF" if any earned runs else "0.00".

Why this case matters

Box scores and stat pages aggregate outs across appearances; thirds of an inning are notorious.
