Why do these three differ? n =. 14 (*: n) | 5729082486784839 147 0 (n*n) | 5729082486784839 147 And where can I find that they are expected to differ? Can I read somewhere how the conversions/promotions are applied? Moreover (!), reading the vocabulary states: ---- For a non-negative integer y, the phrase x ^ y is equivalent to */y # x ---- thus n^2 should be---if I understand the vocabulary---the same as */2 # n , but the latter gives the "correct" (*/2 # n) | 5729082486784839 147 . Thus, I am puzzled... Thanks!
