Now that we can do binary representation without #: or #. please write a
two's-complement representation tcr without using #: or #. .
tcr _2
1 0
tcr i: 2
1 1 0
1 1 1
0 0 0
0 0 1
0 1 0
A straightforward two's-complement value tcv explains the two's
complement representation:
tcv =: ([: (2 p.~ |.) -@{. , }.)"1 NB. two's-complement value
tcv tcr _2
_2
tcv tcr i: 2
_2 _1 0 1 2
