I would like to use that to create an IsNan static method for vtkMath:<BR>

</SPAN></FONT><FONT SIZE="2"><FONT FACE="Consolas, Courier New, Courier"><SPAN STYLE='font-size:10pt'>int vtkMath::IsNan(double x)<BR>
{<BR>
return isnan(x);<BR>
}<BR>
</SPAN></FONT></FONT><FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'><BR>
Does anyone know any portability issues with this?<BR>
