Show the working
- Hits = 150
- At bats = 500
- Walks = 60
- Hit by pitch = 5
- Sacrifice flies = 4
- Total bases = 250
- Earned runs allowed = 70
- Innings pitched = 190
- Batting average = 150 / 500 = 0.3
- Plate appearances = 500 + 60 + 5 + 4 = 569
- On-base percentage = 569 > 0 ? (150 + 60 + 5) / 569 : 0 = 0.377 856
- Slugging percentage = 250 / 500 = 0.5
- OPS = 0.377 856 + 0.5 = 0.877 856
- Isolated power = 0.5 - 0.3 = 0.2
- Earned run average = 70 / 190 * 9 = 3.315 79
- Walks plus hits per inning = 190 > 0 ? (150 + 60) / 190 : 0 = 1.105 26
Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.
