Is there a faster way to compare two variables?

Question

I have this piece of code where Shark tells me about this bottleneck:

CGFloat shortestDistance = (distanceA < distanceB) ? distanceA : distanceB;

all of these values ​​are CGFloat. Is there a faster way to find out which one is smaller and assign it to the shortest? Maybe even by reference instead of copying the value? How do I do this and how can I access this later?

btw is code that runs in a very compressed loop. about 60 times per second.

Answer 4

From the memory of modern CPUs, there are from 6 to 9 pipelines, which is even more likely since I last checked. What you usually consider a heavy processor is actually very small as soon as the optimizer gets to it.
