Hmm..
So I should have used 3 u: 7 u: instead of using 3 u: directly.
Thinking about this further
N=: ".0 :0-.LF
117 205 158 204 153 204 157 205 153 204 151 204 151 205 150 110
105 204 187 99 204 184 204 152 204 188 204 173 205 150 204 172
204 178 111 205 158 100 204 168 204 174 204 186 204 170 204 169
205 150 101 205 152 204 171 204 163
)
(4 u: N) -: N {a.
1
But 4 u: N does not look like N{a.
But I guess that that should be ok, because something analogous
happens with numbers:
M=:2^31
M
2.14748e9
x:M
2147483648
M-:x:M
1
I guess I have to keep in mind that it can never be perfect.
Thanks,
