How to cut off decimal in Java WITHOUT rounding?

Question

I have a series of Java decimals like:

0.43678436287643872
0.4323424556455654
0.6575643254344554

I wish to cut off everything after 5 decimal places. How is this possible?

Answer 1

The DecimalFormat could also be of assistance here:

    double d = 0.436789436287643872;
    DecimalFormat df = new DecimalFormat("0.#####");
    df.setRoundingMode(RoundingMode.DOWN);

    double outputNum = Double.valueOf(df.format(d));
    String outpoutString = df.format(d);

Answer 2

Double.parseDouble(String.valueOf(x).substring(0,7));

OR

Double.valueOf(String.valueOf(x).substring(0,7));

where x contains the value you want to cut such as 0.43678436287643872
