pfpu command: print results always as hex dump and as floats

wpwrak · wpwrak · commit 57592ac11e6b · 2012-01-15T14:14:25.000-03:00
Before, main_pfpu tried to be a bit too smart and made the output
format follow the input format. More often than not, this turned
out to be inconvenient. Now we just print both - let the user
sort them out.
