That reminds me. Is there a way to store a float (32 bits) in 30 bits?

What I mean is, I want to use 2 bits as a seperate field. I tried
using the lower two bits, thus shaving some accuracy of the mantissa,
but this does not always seem to work (SIGFPE from time to time).

Is there a reliable way?
