Examples

{
  double value1 = DoubleConverter.toNullableDouble("ABC"); // Result: null
  double value2 = DoubleConverter.toNullableDouble("123.456"); // Result: 123.456
  double value3 = DoubleConverter.toNullableDouble(true); // Result: 1
  double value4 = DoubleConverter.toNullableDouble(new Date()); // Result: current milliseconds
