I made a function that can end up dividing by zero. When a macro divides by
zero, it just generates a warning and moves on. Functions, however, generate
errors, so on the off chance that the divisor is exactly zero, you can't render
the scene. I've tried using both (A?B:C) and select(A,B,C) to make it avoid
division by zero, but both generate an error when used in a function. Is there
any way to use a conditional in a function?

  select(). You must have some other error in your function.
