bitand~ Bitwise and signal operator. Bitwise and signal operator. Can perform bitwise boolean operations on a floating point signal as bits or as an integer. Note that if you are converting the floats to ints and back that single precision floating point values only retain 24 bits of integer resolution. The floating point bits from left to right are <1 sign bit> <8 exponent bits> <23 mantissa bits>.
