ieee float -1#nan value

Hi,
I accidentally stuff the value of 0xFFFF into a float variable (fVal). My emulator shows me its value is -1#nan (not a number) and my limit clipping code did not work on this value

ie,

if (fVal > fMax) fVal = fMax;
else if (fVal < fMin) fVal = fMin;

You'd think that the fVal would always be inside the limits of fMin and fMax for all values of fVal, but the code did not work when fVal contains the -1#nan value. How should I handle this? Is this a compiler bug?

Thanks
Andy
