最后,我们来展示如何在代码中使用我们定义的注解KeepTwoDecimalPlaces来实现不需要四舍五入的取两位小数。 publicclassTest{@KeepTwoDecimalPlacesprivatedoublevalue=3.456;publicstaticvoidmain(String[]args){Testtest=newTest();doubleresult=DecimalUtil.formatDecimal(test.value);System.out.println(result);// 输出结...
BigDecimal bigDecimal=newBigDecimal(numStr);double doubleNum=bigDecimal.setScale(2,BigDecimal.ROUND_HALF_UP).doubleValue();/** * String s=String.format("%.2f",d); *若double d=0.6566,输出结果为0.66; *若double d=0,输出结果为0.00; */String keepTwoDecimalPlaces=String.format("%.2f",doubleN...
I am trying to keep two decimal places, even if then numbers are zeroes, using DecimalFormatter: DecimalFormat df = new DecimalFormat("#.00"); m_interest = Double.valueOf(df.format(m_principal * m_interestRate)); m_newBalance = Double.valueOf(df.format(m_principal + m_interest - m_p...
首先,我们定义了一个静态方法roundToTwoDecimalPlaces,该方法接受一个double类型的参数number,并返回保留两位小数四舍五入后的结果。 在roundToTwoDecimalPlaces方法中,我们使用了Math.round方法将number乘以100后进行四舍五入,并将结果除以100.0得到保留两位小数四舍五入后的结果。
Each test case contains a char C (+,-,*, /) and two integers A and B(0<A,B<10000).Of course, we all know that A and B are operands and C is an operator. Output For each case, print the operation result. The result should be rounded to 2 decimal places If and only if ...
08.out.println("15.5 -> "+ currencyFormat.format(15.5)); 09.out.println("15.54 -> "+ currencyFormat.format(15.54)); 10.out.println("15.345 -> "+ currencyFormat.format(15.345));// rounds to two decimal places 11.printCurrencyDetails(currencyFormat.getCurrency()); ...
UsingBigDecimalclass is the recommended approachfor doing numerical operations in Java.BigDecimalis animmutableclass and provides operations for arithmetic, scale manipulation, rounding, comparison, hashing, and format conversion. TheBigDecimal.setScale()method takes two arguments. The first isscalei.e. ...
123456.789 ###.## 123456.79 The value has three digits to the right of the decimal point, but the pattern has only two. The format method handles this by rounding up. 123.78 000000.000 000123.780 The pattern specifies leading and trailing zeros, because the 0 character is used instead of the...
Two types of operations are provided for manipulating the scale of a BigDecimal: scaling/rounding operations and decimal point motion operations. Scaling/rounding operations (#setScale setScale and #round round) return a BigDecimal whose value is approximately (or exactly) equal to that of the oper...
