This keeps the “type only” rule for how the operator is interpreted (which i agree with 100%). it also avoids surprises since, like other binary operators, if both values are integers you get an integer result (with the exception of division).

as 1 // (x^n) would result in always returning 0 anyway except when
x==0 (returning NaN), x==1 (returning 1 for all n), or x ~= 0 && n==0
(returning 1 for all x).
Now, if you change that definition to be / instead of //, thus
implying that it returns float instead of int, then that's perfectly
reasonable in my book.
