如何将变量声明为 const int？
我正在尝试将计算的整数插入到平滑移动平均线的表达式中。
我有以下代码：
float timeframe = str.tonumber(timeframe.period)
float timeframefactor = 5/timeframe
int MA200Factor = math.round(200*timeframefactor)
int MA50Factor = math.round(50*timeframefactor)
int MA20Factor = math.round(20*timeframefactor)
然后我用 SMMA 行进行长度跟踪：
len200 = input.int(200, minval=1, title="200 SMMA", group = "Smoothed MA")
我希望用 MA200Factor 替换“200”。但是，当我执行此操作时，会出现错误，指出该值需要为 const int。我不知道该怎么做。
I am trying to insert a computed integer into an expression for a Smoothed Moving Average.
I have the following code:
float timeframe = str.tonumber(timeframe.period)
float timeframefactor = 5/timeframe
int MA200Factor = math.round(200*timeframefactor)
int MA50Factor = math.round(50*timeframefactor)
int MA20Factor = math.round(20*timeframefactor)
I then have followed this up with an SMMA line for length:
len200 = input.int(200, minval=1, title="200 SMMA", group = "Smoothed MA")
I would like the MA200Factor to replace the "200". However, when I do this, it comes up with an error saying the value needs to be const int. I don't know how to do this.

你不能。
const int意味着它的值必须在编译时已知。因此，您不能为该参数使用变量。You cannot.
const intmeans its value must be known at compile time. Therefore you cannot use variables for that argument.
