Changes in 1.9.15 (since the 1.9.14 prerelease): +** `expt' and `integer-expt' changes when the base is 0 + +While `(expt 0 0)' is still 1, `(expt 0 N)' for N > 0 is now 0, and +`(expt 0 N)' for N < 0 is now a NaN value, and likewise for +integer-expt. This is more correct, and conforming to R6RS, but seems +to be incompatible with R5RS, which would always return 0 for all values +of N. + ** And of course, the usual collection of bugfixes Interested users should see the ChangeLog for more information. |
