Bug ID: 496398
Summary: printf changed between RELEASE=24.10 and RELEASE=24.04
Classification: I don't know
Product: kde
Version: unspecified
Platform: Kubuntu
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: general
Assignee: unassigned-b...@kde.org
Reporter: kde....@linwin.com
Target Milestone: ---
core utility printf does not handle decimal parts of numeric values correctly.
Instead of decimal part of a variable it just dumps this text
"-nan"
Previous printf version works fine.
Example in bash environment on 2 systems:
===== system 1
$> cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=24.10
DISTRIB_CODENAME=oracular
DISTRIB_DESCRIPTION="Ubuntu 24.10"
$> ll /bin/printf
-rwxr-xr-x 1 root root 59992 Jul 31 08:24 /bin/printf
-----
$> price='123.4387'
$> count=1200
$> printf "%.2f %4d\n" $price $count
-nan 1200
$> printf "%.5d %.2f\n" $count $price
01200 -nan
===== system 2
$> cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=24.04
DISTRIB_CODENAME=noble
DISTRIB_DESCRIPTION="Ubuntu 24.04.1 LTS"
$> ll /bin/printf
-rwxr-xr-x 1 root root 55744 Apr 5 2024 /bin/printf
-----
$> testVar=8753.2893
$> count=734
$> printf "%5d %.2f\n" $count $testVar
734 8753.29
$> ./printf "%5d %.2f\n" $count $testVar
734 8753.29
Note dot slash is printf from the "other system" in both cases.
Rounding numbers works fine.
What changed in printf program between April and October?
$> diff /bin/printf printf
Binary files /bin/printf and printf differ
$> ll /bin/printf printf
-rwxr-xr-x 1 root root 55744 Apr 5 2024 /bin/printf
-rwxr-xr-x 1 raffi raffi 59992 Nov 17 12:41 printf
