A multi-bit integer value is implicitly converted to a boolean predicate (such as in an if statement or loop condition).

This is not necessarily wrong but can indicate mistakes where you intended to compare the value to something.

module fly;
  int i;
  initial if (i + 2) begin
  end
endmodule

module fly;
  int i;
  initial if (i + 2 != 0) begin
  end
endmodule
