I can't believe I'm saying this, but it would be nice if it behaved like null in SQL.

  That just means you get the problem even further away from the condition that generated it - perhaps your whole query returns NULL. You want the opposite, fail-fast so that you can see what the specific problem was. Signalling NaNs are the way to go unless you have very specific performance requirements.

    You can only rely on the compiler correctly compiling code with signaling NaNs if you use '#pragma STDC FENV_ACCESS ON', but Clang doesn't even support that.

      If your language can't use signalling NaNs correctly, get a better language.
