It's actually not very different from graphic programming, where a simple rounding error can cause all kinds of troubles, from very small (surfaces or ray not reflecting perfectly where they should be) or very big (completely messing your entire rendering). Both activities very much resemble chaotic systems and they are both very challenging to debug.
