https://communities.sas.com/t5/SAS-Procedures/How-to-change-the-length-of-numeric-variable/m-p/17650#M3384 Hi,<BR /> <BR /> I ran a proc means procedure to get mean and standard deviation for my data. However, the length for them are 12, eg, mean=0.0578154391, std=0.0245687672. I only want to have 3 decimal places and total length is 5, that is, mean=0.057, std=0.024, and they still have to be numeric. How should I do it? Thank you very much.<BR /> <BR /> Lu Fri, 15 Oct 2010 16:02:21 GMT lueryy2000 2010-10-15T16:02:21Z https://communities.sas.com/t5/SAS-Procedures/How-to-change-the-length-of-numeric-variable/m-p/17650#M3384 Hi,<BR /> <BR /> I ran a proc means procedure to get mean and standard deviation for my data.

I also used the output statement in proc means prodecure and get a sas dataset: data1 to include the mean and std, I mean how to change the length of mean and std in data1.<BR /> <BR /> Lu Fri, 15 Oct 2010 16:20:08 GMT https://communities.sas.com/t5/SAS-Procedures/How-to-change-the-length-of-numeric-variable/m-p/17652#M3386 lueryy2000 2010-10-15T16:20:08Z https://communities.sas.com/t5/SAS-Procedures/How-to-change-the-length-of-numeric-variable/m-p/17653#M3387 Do you really want to round the values or do you just want to change the format for when they are displayed? You can use proc datasets to change the format of the output dataset.

Your reply reminded me the round function, by which I can change the decimal place for mean and std.
