Changing data in an int array to a double array

[avenhor]

currently I have a two dimensional array that has been defined as int. I would like to redefine or copy these data into another array, but a double array instead. How do I do that?

Currently I've used cast and I've also tried to define the original array as double, but if I do that then the values stored in the original array becomes some very large negative number.

Hi,
if you want copy data from int to double you need
only set double value to int value.
i hope i understand you correct. example :

  int a[3][4];
  double b[3][4];
  for(int i=0; i<3; i++)
    for(int j=0; j<4; j++)
    {
      a[i][j] = i + j;   
      b[i][j] = a[i][j]; //double val = int val
      printf(&quot;\n a[%d][%d] = %d&quot;,i,j,a[i][j]);
      printf(&quot;      b[%d][%d] = %.2e&quot;,i,j,b[i][j]);
    }
