Convert String to Double while maintaining content

Question

I need Java to convert a String which has a binary value (Ex: "0111010") for a double. I tested:

String teste = "101010101";
double number = Double.parseDouble(teste);
System.out.println("The number is: " + number);

But the output is a completely different hexadecimal number. I need the output to be the same as the String. The double can even put point somewhere, no problem, but need to keep the same binary and in the same order.

Answer 1

I couldn’t reproduce the problem. It worked for me. Of course, it appeared in scientific notation. If your wish is to present in floating point notation, then you need to use the function that allows you to format the presentation:

System.out.printf("The number is: %f", number);

Behold working in the ideone. And in the repl it.. Also put on the Github for future reference.

Documentation of the formatter.
