如何在JSP中将数字转换为K千M亿和B十亿后缀

从这里改编答案，看起来应该像

public static String withSuffix(long count) {    if (count < 1000) return "" + count;    int exp = (int) (Math.log(count) / Math.log(1000));    return String.format("%.1f %c",   count / Math.pow(1000, exp),   "kMGTPE".charAt(exp-1));}

测试代码：

for (long num : new long[] { 0, 27, 999, 1000, 110592,       28991029248L, 9223372036854775807L })   System.out.printf("%20d: %8s%n", num, withSuffix(num));

输出：

        0:        0       27:       27      999:      999     1000:    1.0 k   110592:  110.6 k         28991029248:   29.0 G 9223372036854775807:    9.2 E
