rounds the value to the nearest integer before formatting.在格式化之前四舍五入。 具体的顺序是:在没有round指令之前,format会先乘上乘数,再截断位数,最后根据要求打印数值。在指定round指定后,先乘上乘数,之后四舍五入,再根据要求打印数值。如果存在fuzz=模糊因子的选项,SAS将会在模糊匹配后再进行四舍五入的操作。

FUZZ Function:Returns the nearest integer if the argument is within 1E−12 of that integer. dim函数:参数是数组名字 do year=1990 to 2004。相当于下面代码,最后year的值是2005。最后会有一个隐藏的output,如果有了有output了,就不会再有隐藏的output。
