None of the constructs below produce a constant, i.e. something that can be combined with other numbers in as in 1 2 3.
Here's one though: 1ad45, ~. 1ad45 , *1j1 0.707107j0.707107 But there is no way to use "ar" (radians) in exact form, only ~. 1ad45 , 1ar0.785398163397448 0.707107j0.707107 It would be much better to say 1ar1r4p1 or 1x0j1r4p1 but the precedence does not allow it. Why is it like that? Are there more compelling cases for as it is right now? Least const and most verbs expression can be such ~. 1ad45 , ^j.o.%4 0.707107j0.707107 See also http://www.jsoftware.com/jwiki/Guides/Constants http://www.jsoftware.com/help/dictionary/dcons.htm --- Oleg Kobchenko <[EMAIL PROTECTED]> wrote: > Note also, there are numerous ways to > designate this point in J > > ~.
