Could someone tell me what the precise definition of tolerant floor is
(or should be) on arbitrary complex arguments?
The way J implements floor (<.) is not completely consistent,
<.a=: _1e_14 , 100-1e_13
_1 100
<.a j.0
0 99
and has a shape something like this around any Gaussian integer (look
in fixed width font):
'....@+m'{~(~.@,i.]) <. 0j0+ j./~i:1e_13j20
.@@@@@@@@@@@@@@++++++
..@@@@@@@@@@@@+++++++

But that's all I know about the issue.
