- and criticizes this statement. We've discussed it over email (he
- kindly apologized for his harsh language) and I think I should write
- it more clearly:
-
- "All business software everywhere uses arithmetic which preserves full
- accuracy".

- i.e. FP is out of the question (unless you represent everything as
- integers and do tests for some MAXINT which is equal to the size of
- the mantissa). I didn't mean that business software uses 32-bit two's
- complement integer representations (god forbid).
-
- I still wait for counter-examples.
