Hi there,
I want to report a bug in the format module using different locales.
It seems that 'number->locale-string' and 'monetary-amount->locale-string'
are broken.
Please see below emails sent to the guile-users mailing list how to
reproduce the behaviour. The Guile version I used was 2.0.13.
Thanks,
-Martin

Looking at the `format' code for option `h' I see the procedure
`number->locale-string' is used.
OK, let's do some experiments:
scheme@(guile-user)> (setlocale LC_ALL)
$2 = "ru_RU.UTF-8"
scheme@(guile-user)> ,use (ice-9 i18n)
scheme@(guile-user)> (number->locale-string 10.0 5)
$3 = "10,0"
scheme@(guile-user)> (number->locale-string .00003 2)
$4 = "3,0e"
scheme@(guile-user)> (number->locale-string .00003 1)
$5 = "3,0"
scheme@(guile-user)> (number->locale-string .00003 3)
$6 = "3,0e-"
scheme@(guile-user)> (number->locale-string .0 3)
$7 = "-0,0"
scheme@(guile-user)> (number->locale-string .0 10)
$8 = "-0,0"
scheme@(guile-user)> (number->locale-string .0 1)
$9 = "-0,0"
Now for the procedure monetary-amount->locale-string:
scheme@(guile-user)> (monetary-amount->locale-string .0 #t)
$10 = "-0.0 RUB "
scheme@(guile-user)> (monetary-amount->locale-string 100000.0 #t)
$11 = "100\xa0000.0 RUB "
scheme@(guile-user)> (monetary-amount->locale-string .00003 #t)
$12 = "3.0e RUB "
And my guile version:
scheme@(guile-user)> (version)
$13 = "2.0.11"
It seems `number->locale-string' is broken. If I do, e.g.
(number->locale-string .00003 10)
it yields
"3,0e-5"
If the last arg decreases, it just trims the number of
characters after comma, which is wrong in this case.
Output for zero is funny, too.
Regards,
Vladimir

I believe these are fixed by commit
4aead68cdb86ca60cc372f0cd558cadda90ddec5.
You’re welcome to do more testing and report back!
Thanks,
