Bytesized floating point: the HiF8 format. Intricate!
Zero is 0x00, so that's nice. And there's only one zero.
There are two infinities, which could be handy.
Range is 2^15 down to 2^-15 (for positive numbers - it's a sign and magnitude system, mostly)
Up to 4 bits of precision, variable. Best precision around 1.0, tapering off for larger and smaller values.
Denormals go down to 2^-22
