Depends of your context. Another way is to have a method that return=20
directly your array of doubles.

- (double *)salaryArray;

You would then be able to call this methods from F-Script and access=20
your array's elements (see the documentation for the Pointer class in=20
the F-Script manual).

No. Your arrays are small. Unless you need to compute things with them=20=

billions of time by second, you should not have any trouble.

Probably. Because then you would be able to directly make use of the=20
F-Script array programming model.
