Find out if you're reading int or double using fscanf

I have a text file that I want to read using C. It contains lines in this format: %d %d (%d or %lf). An example of 3 lines:

1 0 44
2 0 84.13
3 1 15.07

But the last number can be either int or double, arbitrary. How can I read from the text file regardless of the data type?

Since float can hold an integer but not vice versa. Just read the data like a float and check if it is an integer using something like 

if(ceilf(f) == f)
{
  i=(int)f;
}
//Here i is an integer and f is the float you read using %f
