求百分比%

import java.text.DecimalFormat
val df = new DecimalFormat("#0.000")
val a=4298
val b=43303
val c=a/b
println(c)
println(df.format(c + 0.000001d))

//4298,43303,124675
import java.text.NumberFormat
val nt = NumberFormat.getPercentInstance
nt.setMinimumFractionDigits(2)
val d=nt.format(a / b)
val e=nt.format(4298 / 124675)
println(d)
println(e)

val f=a/b
val i=4298 / 124675
println(f)
println(i)

import java.text.NumberFormat
val num1 = 4298
val num2 = 43303
// 创建一个数值格式化对象
val numberFormat = NumberFormat.getInstance
// 设置精确到小数点后2
numberFormat.setMaximumFractionDigits(2)
val result = numberFormat.format(num1.toFloat / num2.toFloat * 100)

System.out.println("num1和num2的百分比为:" + result + "%")
