Hello all!
I am new to sas and I am stumped with one of my numeric variables.
So, I have a variable name 'sampleid' which is 14 digits long- no space or dots or commas. When I imported my csv file to sas the sampleid of 020613020202021 looks like this: 2.02E+12. Can anyone help with that?
Thanks!
Proc Import in addition to guessing variable types defaults to a "best" format for non-date or time variables.
You can get more digits displayed by assigning a format with more allowed digits such as best14. or F14.
Note that your variable is being treated as numeric so your leading zeroes would require a Z14. format to show them.
You can change the format a number of ways. Best is at reading.
Data mytable;
set mytable;
format sampleid z14.;
run;
is inefficient but simple. Proc datasets can modify formats of variables in place. Or the point-and-click on the table column header should allow setting the format.
If it is really an ID then you probably will want to read it as character instead of reading it as a number. 14 digits is close to the maximum integer that SAS can store uniquely in a numeric variable.
23 data _null_; 24 x=constant('exactint'); 25 put x= comma24. ; 26 run; x=9,007,199,254,740,992
