Show the working
- Number ranked below you = 340
- Number with the same score = 5
- Total in the group = 500
- Percentile to look up = 90
- Percentile rank = (340 + 0.5*5) / 500 * 100 = 68.5
- Percentage above you = 100 - 68.5 = 31.5
- Position from the top = 500 - 340 - 5 + 1 = 156
- Position needed for the target percentile = ceil(500 * (1 - 90/100)) = 50
Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.
