Hi,
Is there a SAS function to calculate the number of digits in a numeric field ?
For example: I have a roll number numeric field. I want the count to show as below
ROLL NUMBER COUNT
1234567 7
12345 5
1212 4
Thank you
If you're working with integers only, then try the approach in the blog post Compute the number of digits in an integer by @Rick_SAS.
data have;
input ROLLNUMBER;
count = ceil(log10(ROLLNUMBER + 1));
datalines;
1234567
12345
1212
;
Result:
ROLLNUMBER count 1234567 7 12345 5 1212 4

thank you @PeterClemmensen . That is exactly what I needed.
If you know the value is an integer (a whole number) then you could just convert it to a string and count the number of digits.
digits=length(cats(whole_number));
