age()
描述：
计算两个时间间隔的年数。
语法：
age(dateExp1:formatExp,dateExp2:formatExp)
备注：
计算dateExp1到dateExp2间隔的整年数。
参数：
|
dateExp1/dateExp2 |
计算结果为日期型(Date)的表达式 ，dateExp2缺省为now()。 |
|
formatExp |
格式化表达式，比如"yyyyMMdd"、"yyyy-MM-dd"。 |
选项：
|
@y |
精确到年。 |
|
@m |
精确到月，缺省精确到日。 |
返回值：
整数
示例：
|
|
A |
|
|
1 |
=age(date("1980-09-01")) |
1980年9月1日到当前间隔的整年数。 |
|
2 |
=age(date("1980-09-01"),date("1985-01-01")) |
4 |
|
3 |
=age@y(date("1980-09-01"),date("1985-01-01")) |
5 |
|
4 |
=age@m("19800227":"yyyyMMdd",date("1999-02-02")) |
