[comp.lang.smalltalk] ST/V Mac Float bugs

mjohnson@cosmos.acs.calpoly.edu (Mark S. Johnson) (03/17/91)

*** Smalltalk/V Mac version 1.1; MacOS 6.05 ***

On my Mac SE/30 at work and my Mac+ at home, both of the Float
instance methods "exponent" and "significand" cause 'Float invalid
operation' walkbacks to appear. These are both primitive methods.

The last "bug" I found turned out to be some "junk methods" left in
for "compatibility" with ST/V 286. However, the methods above do not
seem like they should fall in this category.

Anyone know of a fix?
Is a complete bug list for ST/V Mac available anywhere?

Thanks in advance, Mark

If you hear of a complete list of bugs, please post information.

I have nearly given up using ST/V Mac because of the bugs --
on a Mac Plus, you can't even divide an integer by a negative integer
without getting garbage. Some of these bugs have been known about
for well over a year, and no maintainance releases. Either they prefer
to support IBM platforms, or they don't support anything very well.
