Hi,
I am trying to take the sum ofa numerical variable but getting the values in exponential. I must retain the sum as whole number as it is because i need it for comparing.
data abc;
x = 9823748762398720570234;
run;
proc sql;
create table temp as
select sum(x) from abc;
quit;
How about this:
proc sql;
create table temp as
select sum(x) as Sum format=32. from abc;
quit;

If your example is typical of your data then you are exceeding the precision of SAS variables, at least as documented in SAS 9.3.
The precision of floating-point values is accurate to approximately 15 digits.

Many thanks for the conclusion
reading some old statistical books. make you data numbers to a converted offset position (1970's), sliders were seen, doing handwork understanding your data and tools.
The pitfall of working with big numbers is losing accuracy not notified.
