// the fixed point equivalent is aligned to the LSB. IEEE applies a nearest-
// even round to the bits it lops off before storing. The mantissa can then

// still there, so the easiest thing is to do it with doubles and grab the low
// 32 bits.

// which makes the trick return signed numbers (at least within the mantissa).
