CS & BC: fix inconsistencies in divide-by-zero error messages#5529
Merged
Conversation
For `/`, say "division by zero"; for `log`, say either "undefined for
0" or "undefined for base 1"; for other functions, say "undefined for
<x> (and <y>)". Also, correct function names for `atan` and
`quotient/remainder` on CS, and correct printing of `-0.0` in
`quotient{,/remainder}` on BC.
Update tests to include the error message strings, and add missing
specs for raising of `exn:fail:contract:divide-by-zero` in docs.
The base-one error message in `log` on CS requires
cisco/ChezScheme#1048.
Fix racket#5527.
