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。 然后,我们在main方法中定义了一个doubl...
The program formats a double value in two formats. var df = new DecimalFormat("#.##"); We create a new instance of theDecimalFormat. We pass it a non-localized pattern string. The pattern defines a format for a decimal value with a dot followed by two decimal places. df.applyPattern("...

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 ...
Where there are two or more variant values each indicating its own semantics, these values should be ordered by importance, with most important first, separated by underscore('_'). The variant field is case sensitive. Note: IETF BCP 47 places syntactic restrictions on variant subtags. Also ...
Thus, you can use format or printf anywhere in your code where you have previously been using print or println. For example, System.out.format(...); The syntax for these two java.io.PrintStream methods is the same: public PrintStream format(String format, Object... args) where format...
