Does anyone know what is wrong here?

Hi,
I'm new to the Ash shell so my apologies if this is well known. In normal maths and other shells and languages I've used, the modulo operator always returns a positive remainder. For example see this discussion (first post so I can't hyperlink it):

isisd
IS-IS(8) Version 0.97.3 IS-IS(8)NAME
isisd - an IS-IS routing engine for use with Quagga routing software.
SYNOPSIS
isisd [ -dhv ] [ -f config-file ] [ -i pid-file ] [ -P port-number ] [ -A vty-address ] [ -u user ] [ -g group ]
DESCRIPTION
isisd is a routing component that works with the Quagga routing engine.
OPTIONS
Options available for the isisd command:
-d, --daemon
Runs in daemon mode, forking and exiting from tty.
-f, --config-file config-file
Specifies the config file to use for startup. If not specified this option will likely default to /usr/local/etc/isisd.conf.
-g, --group group
Specify the group to run as. Default is quagga.
-h, --help
A brief message.
-i, --pid_file pid-file
When isisd starts its process identifier is written to pid-file. The init system uses the recorded PID to stop or restart isisd.
The likely default is /var/run/isisd.pid.
-P, --vty_port port-number
Specify the port that the isisd VTY will listen on. This defaults to 2608, as specified in /etc/services.
-A, --vty_addr vty-address
Specify the address that the isisd VTY will listen on. Default is all interfaces.
-u, --user user
Specify the user to run as. Default is quagga.
-v, --version
Print the version and exit.
FILES
/usr/local/sbin/isisd
The default location of the isisd binary.
/usr/local/etc/isisd.conf
The default location of the isisd config file.
$(PWD)/isisd.log
If the isisd process is config'd to output logs to a file, then you will find this file in the directory where you started isisd.
WARNING
This man page is intended to be a quick reference for command line options. The definitive document is the Info file Quagga.
DIAGNOSTICS
The isisd process may log to standard output, to a VTY, to a log file, or through syslog to the system logs. isisd supports many debugging
options, see the Info file, or the source for details.
