Formatting decimal points after using Cat function

[hwangnyc]

Hi everyone,

I have a mean, lower CI variable and upper CI variable. I would like the combine them into one variable. The issue is the CI variable has a long decimal trail. I would like to limit it to two decimals after using the Cat function. So here is my code currently:

data have;
input Mean  :  lowerCLmean : upperCLmean;
cards;
45               30.123456                         50.789123
20               15.789123                         30.123456

;

data want;
set have;
new=cat(mean,' (',lowerclmean,'-',upperclmean,')');

proc print;run;

What I really want:

Obs Mean lowerCLmean upperCLmean Really Want

2

20

15.7891

30.1235

20 (15.78-30.12)

Thanks in advance!

data want;
set have;
new=cat(mean,' (',put(lowerclmean,f5.2 -L),'-',put(upperclmean,F5.2 -L),')');

You can nest all sorts of functions inside the cat, cats, catt, catx etc. functions as long as the results are strings.

Thank you Ballard! Can you tell me what the  "-L" does?

The -L left justifies the result. if your value were actually 9.33 without the -L there would be a leading space as the F5.2 format will display the result in 5 columns and right justified by default: " 9.33" . Since it appeared that you did not want the CI to look like ( 9.33-12.75) for example I used that option.

Character formats will default to left justification but if you want right justification when using Put with a character format you could use put(somevar,$charfmt. -R) which may appear better for some table row headers or graph axis values.
