How to create a variable that has values in increments of .01, and that ranges from -4 to 4?

Hi All,

Can someone please explain to me how to create a variable that has values in increments of .01, and that ranges from -4 to 4. There should be no duplicate values.

For example,

-4.00

-3.99

-3.98

all the way to 4.00.

Thank you

Here's a recommendation that avoids some of the approximations produced by floating point arithmetic:

data want;
   do n=-400 to 400;
      newvar = n / 100;
      output;
   end;
keep newvar;
run;

Here one way to go:

data want;
  do var=-4 to 4 by 0.1;
    var=round(var,.00001);
    output;
  end;
run;

This approach will also achieve what I want. I only can accept one approach as the solution, however.
