hi everyone,
I meet a strange problem, I want to get the square root vale of a number. Here are two functions I found
1. #import <e32math.h>
Sqrt(TReal &,const TReal &)
2. #import <MATH.h>
IMPORT_C double sqrt(double);

I found these functions in SDK of N97, however, I have no idea of how to use them.
Can anyone give me some examples of the usage of these functions? How to fill in the parameter part of these two functions?

Thanks a lot
