The ISO standard, chapter 9.2.1 Reduction, allows
2 different variants for reduction called the
Enclose-Reduction-Style (aka. APL2 style) and the Insert-Reduction-Style
(aka. Sharp/J style).
GNU APL use
I see. Will test this later.
Unequal to zero or one or > 1, because they are vector of length 1 rather than
boolean scalar ?
what about {1+(divide)⍵}⍣5 ⊢ 1
in that case, 5 would not be a boolean. scalar, yes, but not boolean.
personnaly I prefer the old def who equiv scalar and vector of leng
Hi Xtian,
the reason is that the arguments of the right function argument of ⍣
have different lengths and are therefore always unequal:
FIB←{ 3↓
{⍵,+/¯2↑⍵}⍣{(↑⍵)≤¯3+⍴⍺ ⊣ ⎕←'debug:' (⍴⍵) 'vs' (⍴¯3+⍴⍺)} ⊢ ⍵, 0 1
}
FIB 12
