Max 6 MSP bitwise operators are broken

WTF?

All the MSP bitwise operators are buggered in Max 6. Try hooking any of them up to to a [dac~], without any input. Horrible horrible horrible fixed-frequency square wave centered around +0.5.

Hmm… problem went away randomly. The post is too old to change the title to "…seemed broken for a minute there", so sorry for crying wolf.

But it got me thinking. The square wave made me wonder if there was some form of anti-denormal square-wave injection at work (maybe it was being inserted into the MSB rather than the LSB of the 64-bit signal)?

It would be good to know if this technique is indeed used – if so, the bitwise operators wouldn’t be 100% exact.

While I’m on the subject, does anyone know if there is a tiny error margin for equality in the MSP comparison operators, or are they bit-for-bit exact?

Argh! It’s come back again. Try this patch to hear the devil square:
