algorithm - 如何编写这个简单的阈值算法？

Question

score = 50;
thresholdMax = 70;
thresholdMin = 30;

if (score > thresholdMax) return 1;
if (score < thresholdMin) return 0;
else return //the fraction between thresholdMax and thresholdMin that score is, as a value between 0 and 1. 

我知道这一定很简单，但我就是想不出怎么写。

我这样试过，但我认为它不起作用:

spread = ThresholdMax - ThresholdMin;
diff = score - ThresholdMin;
return Math.round(diff / spread);

您也可以尝试使用 min 和 max 函数:

return min(1, max(0, (score-thresholdMin)/(thresholdMax-thresholdMin)));
