Round age

[NewUsrStat]

Dear all, 

suppose to have two dates: 

Date of Birth: 01JUL1936

Date of Admission: 03MAR2016

The age at admission calculated as: (Date of Admission-Date of Birth)/365.25 = 79.67. 

Since I need an integer, should this age be rounded to 80 or not? If yes, how? 

Thank you in advance

Should it be rounded? Well, that's up to you, it depends on how you intend to use the result.

How to round it?

age_rounded = round(yrdif(date_of_birth,date_of_admission,'AGE'));

Use the YRDIF function with its default basis of AGE.
Age is not rounded up for the uses I know. You may have different business rules, though, but only you can know them.

Good point, @Kurt_Bremser about not rounding up

To round down, you would use the FLOOR function in SAS
