See the help on -precision-. You need a -double-.
. set obs 1
obs was 0, now 1
. gen double x1 = 3333^3
. gen x2 = 3333^3
. format %21x x*
. l
+-----------------------------------------------+
| x1 x2 |
|-----------------------------------------------|
1. | +1.13dd59efa0000X+023 +1.13dd5a0000000X+023 |
+-----------------------------------------------+
. format %15.0f x*
. l
+---------------------------+
| x1 x2 |
|---------------------------|
1. | 37025927037 37025927168 |
