data have;
input Group $ Value $
datalines;
BBBB $250
CCCC $500
;
run
I did the following;
data want;
set have;
val_1 = input(Value,8.); Also tried other numeric such as 12 to convert to a numeric
run;
My results do not convert to a number. Instead I get error message such as
Invalid argument to function INPUT
Is it because even though it shows as a character it includes dollar signs. How can I get this to convert to a numeric.
data have;
input Group $ Value $;
datalines;
BBBB $250
CCCC $500
;
run;
data want;
set have;
val_1 = input(Value,dollar8.);
run;
data want1;
set have;
val_1 = input(Value,comma10.);
run;
Alternatively you may try below code
data have;
input Group $ Value $;
datalines;
BBBB $250
CCCC $500
;
run;
data want;
set have;
val_1 = input(compress(Value,,'kd'),best.);
run;
@Q1983 Thank you for posting the $ currency question as I ran into this need just a few moments ago.
@Jagadishkatam Your alternative though looks nice by stripping chars and keeping digits, but is far slower than the straight forward offered one by @novinosrin
I just tested with about 20 million records and your solution exponentially gets slower as I increase the test with adding number of records. Could you offer something that is rather better to beat that ?
@Allaluiah Oh well, it's interesting that you tested the solutions offered here and I appreciate the feedback. I didn't quite expect the diligence by folks on this community for simple solutions.
Ok here you go, this is another one which beat the two variants I posted. So I beat myself . lol
data want;
set have;
val_1 = input(substr(value,2),8.);
run;
And here is my Log report of my test with 30 Million observations
932 /*Compress char and keep digit*/
933 data want;
934 set have;
935 val_1 = input(compress(Value,,'kd'),best.);
936 run;
