Type conversion of a whole array: is it possible?

New comment
 

Hello everybody,

in my code I use a function that calculates the average value of an array of type double:

 

double Average(double &arr[])
  {
   int size=ArraySize(arr);
//--- check
   if(size<=0)
     {
      Print(__FUNCTION__+": array size error");
      return(EMPTY_VALUE);
     }
//--- calculation
   double sum=0.0;
   for(int i=0;i<size;i++)
      sum+=arr[i];
//--- returning the result
   return(sum/size);
  }

The problem I have is that then I need to apply them to an array of type int, as for example:

 

int myarr[5]
for (int i =0; i < 5; i++)
   {
myarr[i]=i+1;
   }

double mymean = Average(myarr);

 But when I compile it I get an error saying that parameter conversion is not allowed. How could I get rid of this? I was thinking about defining a new array of type double and then assigning to it the values of the previous array, and then calculating the average on this array, but this seems quite abstruse to me:

double myarrdoub[5];

for (int i=0; i<5; i++)
{ 
  myarrdoub[i]=myarr[i];
}

mymean=Average(myarrdoub);
 
You have to define a second function with an int as parameter. Or eventually use a template.

Thanks a lot. Could function templates be put in an .mqh file to include in the Expert Advisor?

Of course.
