## Calculate AGE using BIRTH and DEATH DATE

Hi,

When trying to calculate the age using death and birth dates, leaves output as 50.7677488 etc. However, displaying  values like this 51 is expected instead of 50.7677488.

```data data1_;
attrib BRTHDAT_ DTHDAT_  length=8 format=date9.;
attrib AGE_D length=3;
set data1;

if BRTHDAT ne . then
BRTHDAT_=datepart(BRTHDAT);

if DTHDAT ne . then
DTHDAT_=datepart(DTHDAT);

if DTHDAT_ ne . and BRTHDAT_ ne . then do;
AGE_D=(DTHDAT_ - BRTHDAT_)/365.25;
end;

proc sort data=data1_;
by SUBJECT;
run;```

Attached is the code.

Any correction that has to be made to display the age right?

Thank you,

Regards,

Nasya

I imagine you are looking for the age to be rounded:

if DTHDAT_ ne . and BRTHDAT_ ne . then do;
AGE_D= round((DTHDAT_ - BRTHDAT_)/365.25);
end;

Alternatively, leave the calculations as they are, but change the attributes of AGE_D:

attrib AGE_D length=8 format=3.;

can ceil function help?

```if DTHDAT_ ne . and BRTHDAT_ ne . then do;
AGE_D=ceil((DTHDAT_ - BRTHDAT_)/365.25);```

or using yrdif and ceil

`   age=ceil(yrdif(brthdat_, dthdat_, 'AGE'));`
