Hello all,
Using SVN 996, configured with RATIONAL_NUMBERS_WANTED=YES, I
observe the following:
⎕PS ← 1 22
÷ ¯2
╔══════════════════════╗
║1÷18446744073709551614║
╚══════════════════════╝
1 ÷ ¯2
╔════╗
║¯1÷2║
╚════╝
÷ 2
╔═══╗
║1÷2║
╚═══╝
1 ÷ 2
╔═══╗
║1÷2║
╚═══╝
The first result above is wrong. Additionally, taking the
reciprocal of any other negative integer yields an incorrect result.
Regards,
Fred
