hi, knvsol,

sas has an unusually generalized round function. See the documentation. An
example is in the below.

Cheers,
Chang

data one;
  input v1;
  v2 = round(v1, 2);
cards;
-1.7
-1.0
-0.5
0
0.7
1.0
1.1
1.4
2.0

/* out lst
Obs     v1     v2
 1     -1.7    -2
 2     -1.0    -2
 3     -0.5     0
 4      0.0     0
 5      0.7     0
 6      1.0     2
 7      1.1     2
 8      1.4     2
 9      2.0     2
