30 wrz 2008 · Use setRoundingMode, set the RoundingMode explicitly to handle your issue with the half-even round, then use the format pattern for your required output. Example: DecimalFormat df = new DecimalFormat("#.####"); Double d = n.doubleValue(); System.out.println(df.format(d)); gives the output:

31 sie 2024 · In this quick tutorial, we’ll learn how to round a number to n decimal places in Java. Java provides two primitive types that we can use for storing decimal numbers: float and double. Double is the default type: However, we should never use either type for precise values like currencies.
The round() method rounds a number to the nearest integer. One of the following: Required. A number to round. A long value (if the argument is double) or int (if the argument is float) value representing the nearest integer to a number.
9 sie 2024 · We can also take advantage of the static methods in the Math class to round a double value to a specified decimal place. In this case, we can adjust the number of decimal places by multiplying and later dividing by 10^n. Let’s check our helper method: double scale = Math.pow(10, places); return Math.round(value * scale) / scale;
