Post #1782130

P.S. Maybe redundantly: @simon_brooke quoted: "... an implementation [of expt] might choose to compute (expt x 3/2) as if it had been written (sqrt (expt x 3))" Note that this is particularly interesting e.g. in an implementation where (sqrt 4) => 2 rather than (sqrt 4) => 2.0 In such an implementation it is likely that (expt 4 3/2) => 8 rather than (expt 4 3/2) => 8.0 @screwlisp
