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). However, when you get 16-bit numbers, - * you do.
