How to print a float with 2 decimal places in Java?

You can use the printf method, like so:

System.out.printf("%.2f", val);

In short, the %.2f syntax tells Java to return your variable (val) with 2 decimal places (.2) in decimal representation of a floating-point number (f) from the start of the format specifier (%).

There are other conversion characters you can use besides f:

• d: decimal integer
• o: octal integer
• e: floating-point in scientific notation

Rounding double to 2 decimal places in an xml file with databinding

Fixed by creating a private String total; inside CartItem

Created getter and setter for total

In the getter:

public String getTotal() {
        return String.format("%.2f", quantity*product.getPrice());
    }

then went to the xml file and simply put in the string total instead of doing the calculation inside of the xml file.

<TextView
    android:text="@{'£' + cartItem.total}" />

How do I convert a double to 2 decimal places?

Remember you can't use

 String.format("%.2f", maltRequiredString);

Because maltRequiredString is string. Correct coding is that you must use float in this function and for that you have to convert your string to float

float f = Float.valueOf(maltRequiredString);  
String test = String.format("%.02f", f);

You can also use this technique for making it 2 decimal

DecimalFormat decimalFormat = new DecimalFormat("#.##");
float twoDigitsF = Float.valueOf(decimalFormat.format(f));

Round Double to 1 decimal place kotlin: from 0.044999 to 0.1

Finally I did what Andy Turner suggested, rounded to 3 decimals, then to 2 and then to 1:

Answer 1:

val number:Double = 0.0449999
val number3digits:Double = String.format("%.3f", number).toDouble()
val number2digits:Double = String.format("%.2f", number3digits).toDouble()
val solution:Double = String.format("%.1f", number2digits).toDouble()

Answer 2:

val number:Double = 0.0449999
val number3digits:Double = Math.round(number * 1000.0) / 1000.0
val number2digits:Double = Math.round(number3digits * 100.0) / 100.0
val solution:Double = Math.round(number2digits * 10.0) / 10.0

Result:

0.045 → 0.05 → 0.1

Note: I know it is not how it should work but sometimes you need to round up taking into account all decimals for some special cases so maybe someone finds this useful.

Java: double: how to ALWAYS show two decimal digits

You can use something like this:

 double d = 1.234567;
 DecimalFormat df = new DecimalFormat("#.00");

Edited to actually answer the question because I needed the real answer and this came up on google and someone marked it as the answer despite the fact that this wasn't going to work when the decimals were 0.
