Dear list
I need to calculate large numbers using STATA. For example, 3333^3 =
37025927037
However, when I calculate it using STATA,
g example=3333^3
format %15.0f
The "example" variable shows the following values: 37025927168, quite
different from the true value.
Do you have any idea about this?
Rodrigo
