Hi everyone,

I'm trying to write a statement that compares two inputs to a number. Depending on which of them is closer to that number, a statement will use the closer variable that in a calculation.

So for example, I have two inputs from a GUI.

x = 44, and y = 52
Whichever one is closer to 51 will be used in an equation (i.e. y)

Does anyone know how I can accomplish this?

Thank you!

What about solving the equal distance ambiguity with for instance

   if abs(x - 51) > abs(y - 51) 
       z = y; 
   else 
       z=x
   end
   if abs(x - 51) == abs(y - 51) 
       z = [x y];
   end

Thanks for your feedback! You're absolutely right, but this is actually being used in a GUI where I prevent x and y from being equal to each other with error messages and a break statement.
