Hi, I recently built a sample code for calculating reciprocal winds for flight simulation purposes. I want to limit user input to numbers from 0-359 inclusive. Nothing like 360 should be entered by user. How can I do this?

You can certainly do this, but do you need to?

-30 and 720 both have unambiguous interpretations as degrees.

Even if you don't want to support negative degrees (admittedly a bit more complex), a simple n % 360 would give 

accurate results,  which shouldn't be surprising to your users.
