Greetings,

All these years of pov... and it seems I only fail now to find a bitwise
operator for integer.

Is there such things already as a bitwise-AND, bitwise-OR, bitwise-XOR
in the SDL ?

I currently would need a XOR, any suggestion ?

  Since the SDL doesn't support integers (only floating point), bitwise
operators seem kind of pointless...

Ok, so I guess you have no objection if I post a patch in p.u.patches
for that purpose on 3.7;

Bitwise operations are sometime useful (just like int()), even if the
result is afterall a floating number (the range with accuracy might be
reduced, but at least it should be fine unless the 52 bits of double
precision mantissa get in the way: for 16 bits, it should still be ok)

Note that such a patch won't make it into 3.7 and likely won't be supported 
in any future version of an official POV-Ray with whatever syntax you use.

It may still be interesting to some though, so go ahead, I would say...
