RE: st: variable format

["Andreas Drichoutis" <adrihout@cc.uoi.gr>]

Well it didn't. I tried gen varnew=round(var,.01) and all it did is to
create a copy of the original variable. Values are displayed with 2 decimals
but the actual value is 7 decimals long.

.
What do you mean when you say the round function doesn't work?  It really
seems like that should be your best bet.

My concern is the actual value and neither the round function works nor
changing the format to  %3.2f  . 

Any other ideas?

...might need to add that if your concern is not the format but the actual
value, you can round them using the round function together with generate or
replace (-help round-). So if you wanted to replace your data you could do
(if x is your variable):

replace x =round(x, .01)
