cannot call method on integer literal

[Book-reader]

fn int main()
{
  1.is_even(); // Error: Integer suffix 'i' is not valid for a floating point literal.
  return 0;
}

as pointed out here this isn't a huge deal:

[lerno]

The question is whether 0. style should be allowed or not. Should double d = 3.; be allowed?

[Book-reader]

My immediate thought would be to disallow it and either add a d suffix to be consistent with allowing 3f, or just require a .0.

[joshring]

could this also be resolved with brackets?

(5.).is_even()

[lerno]

It could be yes. The question is what the best solution is for C3.
