/*
* 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

*
* - if the value is positive
* we can pass it directly off to the equivalent wuint
* - if the value is negative
* we do the following computation:
* mb + val + 1, where
* mb is the maximum unsigned value in that byte size
* val is the Javascript negative integer
*
*
* As a concrete value, take -128. In signed 16 bits this would be 0xff80. If

* 0xffff - 127
