+/- 1e-45 to 3.4e38. granted, roughly half of that is between -1 and 1.

When we worked with low power silicon, much of the optimization was running with minimal headroom - no point railing the bits 0/1 when .4/.6 will do just fine.

You may want an adder. Wiring two circuit outputs directly together makes them fight, which is usually bad for signals.
