print("Area = ", round(area, 2)) Output: Area = 78.54 💡 Method 3: Using the Decimal Object Another workaround to our problem is to use the Decimal object, and the quantize function to return a float value with two decimal places. quantize method returns a value by rounding the fi...
There are multiple ways to round a double or float value into 2 decimal places in Java. You can use one of the following methods: The DecimalFormat class The BigDecimal class The String.format() method The Math.round() method Note: If you are formatting a currency, always use the ...

To round a number up to two decimal places in Java, you can use the Math.ceil method and multiply the number by 100, then divide the result by 100. Here's an example of how you can do this: double num = 3.14159; double rounded = Math.ceil(num * 100) / 100; This will round ...
