```so?

gen newweek=cond(week<1.5,1,                  ///
cond(abs(round(week,12)-week)<=2,round(week,12),week))

```
```Thank you, Jeph and Martin. This was really helpful.

To add further, is it possible to add another condition to round off weeks
```
0 and <1.5 to become 1 instead of zero while keeping the previous
```condition alive?

Good solution, and in one line. Careful with 1 and 2, though. Does Ali
really want them to become zero?

*************

set obs 30
gen weeks=_n
gen newweek=cond(abs(round(week,12)-week)<=2,round(week,12),week)

```Hi listers,

```
I want to round a variable 'week' if it is within 2 weeks range of multiples of 12 week. So 10 weeks should become 12 weeks while 9 weeks should not change. Similarly 21 weeks would not change while 25 weeks will change to 24 weeks. Is there a way to do it in Stata using -round- or other command?
```
Thank you,
