Index in for loop shows up as a decimal when adding an int

[BryanNorden]

When adding an int to the index for loops it displays as a float instead of an int.

Example

let index = 0
index + 1 should equal and show up as 1 . However, it shows up as 1.0, 2.0, 3.0, etc

#for(player in players) { <tr><td>#(index+1)</td><td>#(player.name)</td></td></tr> }

Expected rendering:

1 Bryan
2 Jessica
3 Chris

How it actually renders:

1.0 Bryan
2.0 Jessica
3.0 Chris

Note:

It could be nice to get a number formatting tag to display it to how the user wants it displayed
