// Conversion functions
//
// There are three reasons for having conversion functions:
//
// 1. We are converting from a signed type to an unsigned type of the same
// size, or vice-versa.
//
// Since we only have unsigned math functions, this allows people to convert
// to unsigned, do the math, and then convert back to signed.
//
// 2. We are converting to a smaller type, and we could therefore possibly
// overflow.
//
// 3. We are converting to a bigger type, and we are signed and the type we are
// converting to is unsigned.
