In other BASICs:
2^-3^4 = 0.000244

Even interpreter/compiler writers can't decide which to do!

HP had a change of heart about that one at some point. The HP-17B/19B/27S evaluate that expression to 0.000244, while the 48 and its successors return 4.135903...E-25. So ^ went from being left-associative to right-associative.
