java里面怎么format number?double i,j;
要把i/j的结果format成含有2位小数的格式, 例如 3.03, 4.00, 120.32 之类的格式.
请问怎么做?
Thanks~

String pattern = "###.##";
double result = i / j;
DecimalFormat Formatter = new DecimalFormat(pattern);
String output = Formatter.format(result);
System.out.println(output);
double result = i / j;
DecimalFormat Formatter = new DecimalFormat(pattern);
String output = Formatter.format(result);
System.out.println(output);
