从数组中删除 "NaN" 值时出现问题
Problem with removing "NaN" values from an array
我无法从数组 (SRprices) 中删除“NaN”值并且只保存数字。 （第 173 行）
我不知道我的代码是否有效，因为我无法像在第一个数组中那样在 table 中打印新数组。 （只检查最后一节）
- 我有两个 table，第一个用于包含 NaN 值的基本数组
第二个 table 是打印只有数字但不起作用的新数组！
我认为问题出在 array.size 但为什么呢？！我不知道
如果有人帮助我，我将不胜感激

您可以只使用 array.copy() 而不是循环来复制您的数组。
你必须从相反的方向遍历数组，否则当你删除一个数组元素时，循环的大小将最终尝试引用一个现在不存在的数组元素，因为数组的大小将不再存在匹配循环的迭代次数。
您有一个声明为 table 的变量，它使用 SRprices 的数组大小作为行数。在第一根柱上，这可能为零，因此在后续柱上，当有更多值时，它不会被修改。要么将大小设置为所需的最大值，要么使用您声明的大小（21）的 array.size(sr_levs)。
