At first you should create label, then set formatted text to text property, and after this show on your view (self.view assumes you use it into UIViewController)

UILabel * label = [[UILabel alloc] initWithFrame:CGRectMake(10, 10, 100, 30)];
[label setText:[NSString stringWithFormat:@"%f", a]];
[self.view addSubview:label];
[label release];
