![]() ![]() ![]() The only rounding mode applicable is half-up. Note that the number of zeros indicates the number of decimals. The following solution demonstrates its usage to round up a double with 2 decimal places. Although, String.format() does not allow to change the rounding mode. Using Math.round () method The Math.round () method returns the value of the specified double rounded to the nearest long value. Using String.format(“%.2f”, floatValue)Īlternatively, you can use String.format() function to format the input value to 2 decimal points. (decimalFormat.format(floatValue)) //11.90ģ. You can use s format() method to format double to 2 decimal places. (decimalFormat.format(doubleValue)) //11.90ĭecimal Format – Round float to 2 decimal points example import Decimal Format – Round double to 2 decimal points example import ĭecimalFormat decimalFormat = new DecimalFormat("0.00") ĭtRoundingMode(RoundingMode.HALF_UP) Let’s have a look at the complete example. Then BigDecimal("0.00") will print 11.90 Rounding Modes: On the other hand, the formatting pattern “0.00” will always display a digit even if it is zero. ![]() When creating a DecimalFormat object, there are two ways to set a formatting pattern:īoth of these formatting patterns work similarly, except that “#.#” will not display a digit if the last decimal point is zero. Round to 2 decimal points DecimalFormat decimalFormat = new DecimalFormat("0.00") ĭtRoundingMode(RoundingMode.HALF_UP) Round to 1 decimal point DecimalFormat decimalFormat = new DecimalFormat("0.0") ĭtRoundingMode(RoundingMode.HALF_UP) Format Pattern “0.00” vs “#.#” DecimalFormat class allows us to create an output pattern and then set a rounding mode that we want to apply to a value. (bigDecimalFloatWithScale) // Prints 11.90Īnother way to round a float or a double value to 2 decimal points is to use the DecimalFormat class. (bigDecimalFloat) // Prints 11.89890003204345703125īigDecimal bigDecimalFloatWithScale = tScale(2, RoundingMode.HALF_UP) For example, we can convert a decimal-based currency value without removing non-numeric symbols: Similar to the Double.valueOf, the DecimalFormat.parse method returns a Number, which we can convert to a primitive double using the doubleValue method. BigDecimal – Round float to 2 decimal points example import īigDecimal bigDecimalFloat = new BigDecimal(floatValue) When a String representing a double has a more complex format, we can use a DecimalFormat. Similarly, you can use BigDecimal to round a float value to 2 decimal points. BigDecimal – Round double to 2 decimal points example import īigDecimal bigDecimalDouble = new BigDecimal(doubleValue)
