* ○ 0j1 × 2e9 + a ÷ 2 1 0J1 ¯1 0J¯1 1 0J1 ¯1 0J¯1 1 0J1 ¯1 0J¯1 (Basically, ^ o. 0j1 * 2e9 + a % 2 where a=: 3 4$i.12) I thought I did the same in J, predating what's done in Dyalog APL. According to https://www.jsoftware.com/help/dictionary/special.htm, there is supposed to be special code for ^@o., but apparently it got lost somewhere, sometime.
