Solution description

The isnanf and isnanl functions are in the Tru64 UNIX Migration Environment.

Applications will be able to use these functions from the Tru64 UNIX Migration Environment for HP-UX. Please note that the Migration Environment is temporary. For a long-term solution, use the isnan macro. The isnan macro determines whether its argument is a NaN (the IEEE floating point reserved non-a-number value).
