This doesn't mean floating point math is Completely Impossible,
it just means you do it by hand. Or you make up your own
format like back in the olden days. Look at the USL/ATT/Whatever
source code for the accounting functions. They contain routines
for 16-bit floating point numbers which work rather well.
