Hello everyone!
I've got a basic question. I'm sure this is a very vast debate, since
I've found several answers on the subject, but I'm not satisfied.
I've read that, since we're programming in Objective-C, it's more
elegant and reliable to use an NSArray stuffed with NSNumber instead
of a classic C array. But what I want to do, it's performing classic
calculation, like mean value, variance... etc, on floating point
numbers. Typically around 1000 of them.
I know that our computers are fast now, but this doesn't mean that we
have to not take care of optimization.
So, since NSArray is designed to store all kinds of NSObject's, and
mine will just store some NSNumber's, wouldn't it be a bit stupid to
use it?
Thanks in advance.
Stanislas
