This is not a problem with the -real()- function at all. The problem lies in your use by default of a -float- variable type.
You need to use a more appropriate storage type, e.g. -double-, to avoid precision problems.
. gen double numven6=real("600010154088")
. format numven6 %18.0f
. l numven6 in 1
+--------------+
| numven6 |
|--------------|
1. | 600010154088 |
+--------------
-search precision- for many sources of further information.

When I use the "real" function with large numbers, I have random results as :
command :
gen numven6=real("600010154088")
i get the following result :
numven6=600010129408
Have anybody had the same problem?
