Looking for a function which counts the number of numeric digits in a variable

[RobertNYC]

Hi all, 

Just like the tile says, I'm Looking for a function which counts the number of numeric digits in a variable. I  know there is an easy answer to this question but can't  seem to find it.  Thanks

ID	Number count
17465	5
571567	6
29	2
144	3
5	1

if your id is char, length function will do

count=length(id);

[RobertNYC]

Sorry I should have specified ID is a numeric variable

AS the variable is char type you can use:

     count = length(strip(ID));

[novinosrin]

Well in that case @Shmuel solution will work for both. However with a log note-->NOTE: Numeric values have been converted to character
values at the places given by: (Line) : (Column).

Depends upon what you want! Should 000123 count as 3 digits, or six?. If it's the latter, you could use:

data have;
  input x $;
  nbDigits = lengthn(compress(x,,"kd"));
  datalines;
1
12
123
123 4
0000123
0.00123
-123
123000
