- ΩSANE Beta Release Version 1.0b4
- January 28, 1991
-
- This beta release of ΩSANE obtains substantial speed-up for floating-point
- arithmetic through SANE toolbox traps. The speed-up applies to all
- Macintosh platforms except the Macintosh LC and the Macintosh IIsi without
- FPU. On these new machines, the SANE toolbox traps have comparable
- performance to “backpatched” ΩSANE, so we have chosen not to install
- on these configurations. ΩSANE will install on a Macintosh IIsi which
- does have an FPU, and will provide enhanced performance. Please see the
- Release Notes for further details on ΩSANE.
-
- The Version 1.0b1 release revealed an error in the binary<->decimal
- conversions which caused an infinite loop (on a vanishingly small set of
- input values); many thanks to the people at Language Systems for uncovering
- this problem. The bug was fixed in the 1.0b3 release (Version 1.0b2
- was an Apple internal release only).
-
- Version 1.0b4 fixes a bug which caused erroneous rounding in certain
- (very infrequent) circumstances, and only when halts were enabled.
