I'll bet you that what you are quoting is a value of a -float- variable. Your punishment is that you got what you asked for, holding results to less precision.
The problem is yours, not understanding what you asked for!
What science are you in that needs precision to 1 part in 10^7? Particle physics?

P.S. It's STATA, not Stata.

I just realized that STATA mistake divisions at 7-8 decimal place!
I know it sounds strange, but try to do 45315 / 19657 ....
SAS: 2.30528564887826
STATA: 2,30528569221496
Excel: 2,30528564887826
Mathematica: http://www.wolframalpha.com/input/?i=45315%2F19657
It's not a good job for a scientific software!!
