I am doing repeated interpolation on a limited domain [x_min, x_max]. Each time I need to check to see if any interpolation points have moved outside the domain bounds. If so, I set them to NaN.

There are other ways to solve this, but I prefer using NaNs as "missing data" flags. If I inadvertently use an NaN elsewhere in my code, I want to generate a floating point exception.
