parts of srfi 159 may be broken #433

Open pclouds opened 4 years ago

pclouds commented 4 years ago

I was trying to run 159 tests and found failed test cases, e.g.

$ ./gxi --lang r7rs
R7RS Scheme in Gerbil v0.16-DEV-478-g695a5915 on Gambit v4.9.3
> (import (std srfi 159))
> (show #f (numeric 0. 10))
"0."
> (show #f (with ((precision 2)) .997554209949891))
"00.1"

The expectation is "0.0" and "1.00".

I can't look into this yet (and no promise to do it) so I'm opening an issue here for you to keep track of it.

If you want to try, you can check out https://github.com/pclouds/srfi-159/tree/portable-implementation-2, here's what I did

That one uses my own implementation (also ported from chibi) not the one that comes with Gerbil. Swapping LOADPATH to prefer Gerbil's shows a few more errors. Some related to pretty procedues which should be fixed by #360. Some others are about columnar...

Thank you for reporting this, i was pretty sure we would have some bugs there.
