Hi all,
I am trying to get the sum of a column in a dataset. I tried using both proc means and proc sql, but in both cases, the number of digits in the sum exceeded the length of the variable. I'm not sure how to program a longer length into either of those functions. I tried to do it in proc sql like this:
proc sql;
create table new as
select sum(var) as sum_var length=50 from have;
quit;
The code worked, but ignored my length statement.
Any help is much appreciated.
Not sure I understand your issue, but the length of numeric variable in SAS is 3-8, with 8 as the default. In other words, assign a length greater than 8 will have no effect.

Tyr this.
proc sql;
create table new as
select sum(var) as sum_var format=best16. from have;
quit;
Check in the documentation the numeric precision chapters.
There are no fixed numbers as all is floating based on internal 8 bytes.
The limit of meaningful digits is about 12
What you are probably looking for is the layout of the result.
That one is the format of the result
