For the most part, J concerns itself with arithmetic properties, and
not the inner details of the way numbers are represented.
However, for whatever reason, plot uses 3!:0 to determine what it
should be doing (rather than letting the user control this, and rather
than using an expression like *./,0={:+.y)
Of course using plot&([EMAIL PROTECTED] ::]L: 0) works around this problem.
