答案

参考答案：B

解析： 本题考查Formats函数的用法。用 Formats函数可以使数值按指定的格式输出。可以在Formats函数中使用的格式有：“#”、“0”“.”、“,”“%”、“＄”、“+”、“-”、“E+”、“E-”。其中一个“#”或一个“0”格式符表示一个数字位，其个数决定了显示区段的长度；“.”格式符用于显示小数点；“,”格式符用于在数值中插入千位分隔符。选项A错误，格式说明符没有用括号括起来；选项B正确，格式说明符用括号括起来，格式符“,”和“.”的位置符合使用规则；选项C错误，格式说明符“,”不能放在格式说明符的头部位置；选项D错误。格式说明符“.”一般与“#”格式符不能放在格式字符中小数点左边的头部和尾部。答案为B。
