# Understanding the reason behind the μ (mu) operator [closed]

• What is the purpose of the $\mu$ operator?
• Is there a real world example?
• Is it correct that it can create partial functions out of total functions and it makes a function $g$ with k parameters out of a function $f$ with $k+1$ parameters?
• What do you mean by "the reason behind the $\mu$ operator"?

• @D.W. The purpose of the μ operator. What does it accomplish. Jul 20, 2014 at 14:21
• @polym It accomplishes what its definition says it accomplishes. I also can't work out what you're asking. Jul 20, 2014 at 14:57
• @KarolisJuodel: I think this is as good an answer as this thin question can receive. Mind posting as one? This question may be a useful reference, too.
