When I make a new sample project, all math.h functions work (and as
far as I know all other C standard library functions), I believe that
these libraries are included in the Cocoa framework. So there might
be some other code of yours conflicting, do you have an object
(variable) called "pow"? You can try to NSLog other math functions
such as sqrt(16) or sin(3.1415) to see whether the problem is indeed
due math.h not being included.
Good luck, Patrick

Hi all,
I am writing a Cocoa app, and for one of my methods, I'd like to
use exponential math. For example, I want to raise 10 to the power
of 3 and store the result. I found the pow() function in math.h,
and read the docs in the man page. So, in my code, I have
something like:
double a = 10;
double b = 3;
double c = pow(a, b);
But when compiling my app, I get a compile error "called object
'pow' is not a function".
I've added #import <math.h> to the top of my .m file. But still
nothing.
How do I get pow() and the other math functions to work in my Cocoa
app?
Thanks.
Nelson
