Tell what is encoded in a float, given its HEX bytes

It handles all possible combination of the hex bytes, including NaNs, Infinities, Normalized and Subnormal Numbers...

This crazy DC stuff spent me a few days to write, optimize, polish and squeeze so that it works within the tight 255 character bound... You can modify it easily for other IEEE754 numbers, say, half, double, double-extended, quadruple (I hope someone will find this useful and submit more dc code to commandlinefu!)

-l auto-selects many more digits (but you can round/truncate in your head, right) plus it loads a few math functions like sin().
