Math calculation and database access

Hi,

We are using NSIS to create installers.

As part of our requirement, we must do some math calculations based on the components selected by the user during installation, once the calculation is done the result must be updated in a MS Access database.

My queries are

The math calculation will be a addition of different numbers which will be power of 2 say power (2,0)+power(2,1) …. Etc.
After the calculation I must update my database (MS Access) with the value. Can I execute queries using NSIS, if so, kindly provide me some samples.

with Regards
A.Rajesh

I am trying to query an Access DB also. if you find a way to do this please let me know.
