From the look of the two lines of C he was commenting on,
it looks like he's only refering to conversion of short to
unsigned short only:

:> Note : when i cast to a SHORT instead of an unsigned short in the first
:> case, ALL compilers give 0x8002
:> (cast to float to short to unsigned short)
:>
:> unsigned short s=(short)((float)(-32766.5));
:> or
:> unsigned short s=(unsigned short)(short)((float)(-32766.5));
