How to build an FPU?

[LBSC]

I want to build a calculating machine called the Zuse1, unfortunately I don't know how to *build* FP hardware, but I can add, subtract, multiply and divide floaties using pen and paper, please help me build the normalizer & barrel shifter, I don't care about rounding.

If you want to stay true to the spirit of the Z1, all gates will have to use pistons. Otherwise, make a Z3
