A little unrelated but it's a question about C :)

Hi,

I'm trying to debug a program and I need to have a printf statement that
will get called when a float variable turns into NaN.

I tried something like

if(VARIABLE == NULL)
{
   printf("%d" , Called_Function_Id);
}

But the compiler doesn't like it. Is there a way to catch a NaN value
like that?

THanks
