strictfp class Example {
public static void main(String[] args) {
double d = Double.MAX_VALUE;
System.out.println("This value \"" + ((d * 1.1d) / 1.1d) + "\" cannot be represented as double.");
}

Note that this This compliant solution also specifies that the floating-point literals (1.1) are of type double to clarify their expected type ; this complies with rule "NUM18-J. Be aware of numeric promotion behavior."and minimize their lack of precision.
