Easiest way to extract specific number - Scan or substring in proc SQL or data step

Stalk — Wed, 26 May 2021 19:17:18 GMT

I would like to extract just the number 27.59 from the following Positive (27.59). Irrespective of the text before the parenthesis.

thank you

SCAN() will work well as long as the text before (or after if searching backwards) does not include parentheses.

number = input(scan(string,1,'()'),32.);

It sounds like you know the number that you are searching for in advance; is that correct? If so, see the code below. I'm using a combination of the FIND, LENGTH, and SUBSTR functions. I'm sure there are other ways to do it as well.

Regards,

Jim

Results:

Code:

DATA	_NULL_;
	Search_For	=	'27.59';
	Search_Len	=	LENGTHN(Search_For);
	Var			=	'Positive (27.59)';

	Number	=	SUBSTR(Var, FIND(Var,'27.59'), Search_Len);

	PUTLOG	"NOTE:  "  Number=;
	PUTLOG	"NOTE-  "  ;
RUN;

Thank you Tom and Jim for the quick response.

I used the following..ct_value= scan(Result,2,'()');

I just need the number with in parenthesis for all the records.
