java求百分比

入参是int 输出字符串或数值可自己调整

public class MathUtil {

    public static String percent(int x, int total) {
        if (total == 0) {
            return "0";
        }
        return new BigDecimal(x).multiply(new BigDecimal(100)).divide(new BigDecimal(total), 1, RoundingMode.HALF_UP).stripTrailingZeros().toString();
    }
    
}
