Is there a cleaner way in objective-c to cap a value between two numbers?

Question

Is there a more concise way to write the following code?

if (myValue > 100) 
  myValue = 100;
if (myValue < 0) 
  myValue = 0;

Thanks in advance for your wisdom!

There are a dozen variations of the same thing. Nothing magical. — Hot Licks, Feb 10 '14 at 00:51

You can use MAX and MIN, though it's not necessarily as clear.

myValue = MAX(MIN(myValue, 100), 0);

I agree, though I still like that better than the four-liner above. Thanks. – BeachRunnerFred Feb 10 '14 at 00:39

myValue = (myValue > 100) ? 100 : myValue;
myValue = (myValue < 0) ? 0 : myValue;

or

myValue = (myValue > 100) ? 100 : ((myValue < 0) ? 0 : myValue);

of course I would use MIN/MAX even if you do 2 lines.

maybe even

#define MINMAX(_min_,_max_,_n_) (MAX(MIN(_n_, _max_), _min_))
