A reminder on how two's complement actually + * works. The first bit is the signed bit, i.e. tells us whether or not the + * number should be positive or negative. If the two's complement value is + * positive, then we're done, as it's equivalent to the unsigned representation. + * + * Now if the number is positive, you're pretty much done, you can just leverage + * the unsigned translations and return those. Unfortunately, negative numbers + * aren't quite that straightforward. + * + * At first glance, one might be inclined to use the traditional formula to + * translate binary numbers between the positive and negative values in two's + * complement. (Though it doesn't quite work for the most negative value) + * Mainly: + * - invert all the bits + * - add one to the result + * + * Of course, this doesn't quite work in Javascript. Take for example the value + * of -128. This could be represented in 16 bits (big-endian) as 0xff80. But of + * course, Javascript will do the following: + * + * > ~0xff80 + * -65409 + * + * Whoh there, Javascript, that's not quite right. But wait, according to + * Javascript that's perfectly correct. When Javascript ends up seeing the + * constant 0xff80, it has no notion that it is actually a signed number. It + * assumes that we've input the unsigned value 0xff80. Thus, when it does the + * binary negation, it casts it into a signed value, (positive 0xff80). Then + * when you perform binary negation on that, it turns it into a negative number. + * + * Instead, we're going to have to use the following general formula, that works + * in a rather Javascript friendly way. I'm glad we don't support this kind of + * weird numbering scheme in the kernel. + * + * (BIT-MAX - (unsigned)val + 1) * -1 + * + * The astute observer, may think that this doesn't make sense for 8-bit numbers + * (really it isn't necessary for them).
