I'm trying to learn Objective C so that I can program for the iPhone. I've been working through Programming In Obective C (Stephan Kochan) and have experimented with making a Point class. However, I can't figure out why this doesn't work if x & y (Point's only instance variables) don't function properly if they are floats, whereas they work fine if they are ints.

-(void) toString {
printf(”(%d, %d)”, x, y);

%d prints a integer
%f is what you want to print a float
