我需要申报另外两个变量,以便将联邦和州的预扣税显示为百分比。
示例他们显示为(00.20%)我需要他们返回整体百分比(20.00%)
我尝试在底部声明新变量,例如:
statewit = sTax * 100;
fedwit = fTax * 100;
让百分比按我的意愿返回,但它往往会在结尾处将总数加到网上。
非常感谢任何帮助,谢谢!
答案 0 :(得分:1)
试试这个。
double percent=12.34;
System.out.printf("%.2f%%", percent);
// or in different convention "percent as number *100"
System.out.printf("%.2f%%", percent*100.0);
编辑:您的问题可分为两部分:
使用数字的惯例(正常或百分比缩放* 100)
真正格式化为字符串
顺便说一下你的代码很长,几乎没有格式化。
Java没有特殊类型的百分比值。类型:double,BigDecimal可以与他的行为一起使用,或者也可以是整数类型,如果程序员保持整数约定
编辑:谢谢Costis Aivalis,逗号更正:)
