Hi,
I need a statement to show
if balance is a minus number then 0.
How is this written please?
Hi,
data want;
set have;
if value < 0 then result=0;
else result=1;
run;
result is 0 for minus numbers, 1 otherwise.
Hi RW9,
Sorry, can i have this in proc sql please?
Hello,
PROC SQL;
select *,
case when age-13 lt 0 then 0
else age-13
end as age_diff from sashelp.class;
quit;
Replace if /then with case/when
case when <condition> then <result> else <default option> end as variable
Can also be
case <variable> when <condition> then <result> else <default option> end
E.g.
case when variable < 0 then 0 else 1 as result
Another approach is to not change the value just how it displays with a custom format:
proc format;
value myneg
low - 0 = 0
other = [best8.]
;
And in any display use that format by adding
Format var myneg. ;
Hi ... another way in SQL ...
data old;
input balance @@;
datalines;
-1 20 56 -99 . 80 100 -0.123
;
proc sql;
select *, balance - (balance lt 0) * balance as new from old;
quit;
balance new
---------------------------------
-1 0
20 20
56 56
-99 0
. .
80 80
100 100
-0.123 0
though if it's just display that's important, the suggestion about using a FORMAT is probably better
