   I suspect that INF means INFinite (which is what some people call the 
result of devision by zero) and NAN means "Not A Number." 

   Some machines have a floating point representation for infinity and a
corresponding integer representation. Such machines may allow operations
that result in infinity and only give an error when infinity is used in
another calculation.  Since the machine has a representation for infinity,
the I/O routines need a way to print this value...hence INF/NAN.
