Question

I’ve been trying to make a specific calculation in xcode with user defined variables. Here’s what I have:

-(IBAction)calculate:(id)sender{
    NSString *oneField = self.one.text;
    NSString *twoField = self.two.text;
    double resultInNum;
    double onedouble = [oneField doubleValue];
    double twodouble = [twoField doubleValue];

And what I need to do, is cube root the outcome of

(twodouble/onedouble)

I can’t quite find away. Any ideas?

Use the pow function from math.h

pow(x, 1.0/3.0)
