String.format也可以用来格式化数字,通过指定格式字符串来实现去掉末尾零的目的。 publicclassRemoveTrailingZeros{publicstaticvoidmain(String[]args){doublenumber=123.45000;Stringresult=String.format("%.2f",number);System.out.println(result);// 输出 123.45}} 1. 2. 3. 4. 5. 6. 7. 解析 在这个示例中...
publicclassRemoveTrailingZeros{publicstaticvoidmain(String[]args){// Step 1: 创建浮点数变量doublenum=12.340000;// Step 2: 使用 String.format 进行格式化Stringstr=String.format("%.10f",num);// Step 3: 使用正则表达式去除尾部的零str=str.replaceAll("0*$","");// Step 4: 输出结果System.out....

If all the digits are zero, // replace with a single 0; otherwise, remove all // trailing zeros. String signif = Long.toHexString(signifBits).substring(3,16); answer.append(signif.equals("0000000000000") ? // 13 zeros "0": signif.replaceFirst("0{1,12}$", "")); answer.append('p...
In this approach, we parse the strings representing the scientific notation into doubles usingDouble.parseDouble(scientificValueString). We then use theformat()method of theStringobject to format the scientific values with up to six decimal places using(%.6f). Further, we remove trailing zeros an...
