Case 1: X and Y are Boolean
R is Boolean is determined as follows:
X Y R 0 0 0 0 1 0 1 0 0 1 1 1
Note that the ASCII caret (^) will also be interpreted as an APL And (^).
Example
0 1 0 1 ^ 0 0 1 1 0 0 0 1
Case 2: Either or both X and Y are numeric (non-Boolean)
R is the lowest common multiple of X and Y. Note that in this case, ⎕CT and ⎕DCT are implicit arguments.
Example
15 1 2 7 ^ 35 1 4 0 105 1 4 0 2 3 4 ∧ 0j1 1j2 2j3 0J2 3J6 8J12 2j2 2j4 ∧ 5j5 4j4 10J10 ¯4J12
