- * Signed integer types, yay team! 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). However, when you get 16-bit numbers,
- * you do. Let's go back to our prior example and see how this will look:
- *
- * (0xffff - 0xff80 + 1) * -1
- * (0x007f + 1) * -1
- * (0x0080) * -1
