Rounding up or down based on conditions >X.5 or <=X.5

[kmardinian]

Hi, If I would like to round up or down for a specific variable in a dataset under these two conditions, what would be the best/easiest way to do this in SAS?

For decimal value outcomes < X.5, round down to the nearest integer

For decimal value outcomes ≥ X.5, round up to the nearest integer

I've seen it done as a do loop, but that seems overly complicated.

Any help is much appreciated, thank you!

This is exactly what the Round Function does?

data have;
   do x=1 to 10;
      y=x*rand('uniform');
      output;
   end;
run;

data want;
   set have;
   z=round(y);
run;

And for extra added fun you can actually round to the nearest multiple of a given number. The default is 1 if not supplied.

data have;
   do x=1 to 10;
      z= rand('uniform');
      y1= round(x*z,1);
      y2= round(x*z,2);
      y3= round(x*z,.7);
      y4= round(x*z,2.5);
      output;
   end;
run;

This is different than the title of this thread, and if you really mean the title of this thread, then the answer given is not correct. Just saying...
