#672: CR: Division by inexact zero results in infinity (or nan) as per IEEE 754
-----------------------------+----------------------------------------------
Reporter: sjamaan | Owner:
Type: defect | Status: new
Priority: major | Milestone: 4.8.0
Component: core libraries | Version: 4.7.x
Resolution: | Keywords: numbers, flonums, IEEE 754
-----------------------------+----------------------------------------------
Comment(by zbigniew):
My only argument against doing this in core is that large exacts may be
coerced to inexact without warning, which would change the result of the
computation from error to inf/nan. (We also know Felix is opposed to
changing the behavior of the / operator in core (fp/ already returns the
correct result)).
However, the numbers egg does not exhibit this problem, so in my opinion,
you should change numbers to return IEEE 754 compliant results.
