I mean that I'm only using the nonnegative integer subset of float. That's 
24 bits, from 0 to 16777215. A 32-bit pointer can fit in two such ints, 
but a 64-bit pointer needs a third such int.

(actually, today's 64-bit pointers use less than 48 bits, so they could 
fit in two floats with some special tricks, but it's not even worth 
thinking about it.)

Not limiting myself to integer floats, though, I could simply cast a 
void** to a float* and call it an array of 2 floats. I don't know why I 
didn't do it that way. Superstitions, prolly.
