Re: possible bug in the fmt egg?

[Kristian Lein-Mathisen]

Hi Kurt,

Thank you for reporting that. Looks like it's been fixed upstream now. The
egg seems to be at 8.11.2 still, but I guess the fix will reach the egg on
next merge/release.

Re: possible bug in the fmt egg?

[T. Kurt Bond]

I'll note that SRFI 166 (which seems to have replaced fmt in chibi-scheme
0.10, which I *think* is Alex Shinn's own scheme) has a issue that seems
similar, but not quite the same:

$ chibi-scheme
> (import (srfi 166))
> (show #f (numeric/si 1024))
"1k"
> (show #f (numeric/si 0))
ERROR in "inexact->exact": exact: not a finite number: +inf.0
> (show #f (numeric/si -1))
ERROR in "floor": invalid type, expected Number: 0.0+0.45479211794728047i

 I suspect the fmt code is related to the SRFI 166 code.  I just tried this
with chibi-scheme head, and it has the same result.  I've add an issue on
the chibi-scheme github repo:

The upstream repository is the CHICKEN Subversion repository.

You can get a copy of it with:

  $ svn co 
https://anonym...@code.call-cc.org/svn/chicken-eggs/release/5/fmt/trunk fmt

The author of fmt is Alex (Cc'ed).

All the best.

possible bug in the fmt egg?

[Kristian Lein-Mathisen]

Hi,

I'm playing with the fmt  egg and I
think I've stumbled upon a problem:

~> csi -R fmt -P '(fmt #f (num/si 1024))'
"1Ki"
~> csi -R fmt -P '(fmt #f (num/si 0))'
Error: (log) log of exact 0 is undefined: 0
klm@pisa ~ [70]> csi -R fmt -P '(fmt #f (num/si -1))'
Error: (floor) bad argument type - not a real: 0.0+0.453236014182719i

I couldn't find the upstream repo to report to, so I thought I'd try here.

Thanks,
K.
