Solution
Hello,

Thanks all for your time. Actually the problem was with the LC_ALL configuration. On the machine where there was arithmetic syntax error it was "fr_FR.UTF-8".

If I set the LC_ALL to "fr_FR.UTF-8" as shown below I can reproduce the problem.

Code:
root(0)> LC_ALL=fr_FR.UTF-8
[/root]
root(0)> locale
LANG=fr_FR.UTF-8
LC_CTYPE="fr_FR.UTF-8"
LC_NUMERIC="fr_FR.UTF-8"
LC_TIME="fr_FR.UTF-8"
LC_COLLATE="fr_FR.UTF-8"
LC_MONETARY="fr_FR.UTF-8"
LC_MESSAGES="fr_FR.UTF-8"
LC_PAPER="fr_FR.UTF-8"
LC_NAME="fr_FR.UTF-8"
LC_ADDRESS="fr_FR.UTF-8"
LC_TELEPHONE="fr_FR.UTF-8"
LC_MEASUREMENT="fr_FR.UTF-8"
LC_IDENTIFICATION="fr_FR.UTF-8"
LC_ALL=fr_FR.UTF-8
[/root]
root(0)> cat /tmp/t.ksh
#!/bin/ksh

i=10
j=10.01

if [ $i -ge $j ]
then
        echo "$i is ge $j"
else
        echo "$j is ge $i"
fi
[/root]
root(0)> /tmp/t.ksh
/tmp/t.ksh[6]: [: 10.01: arithmetic syntax error
10.01 is ge 10

To solve the problem, set LC_ALL=C.

Code:
root(0)> LC_ALL=C
[/root]
root(0)> /tmp/t.ksh
10.01 is ge 10
[/root]

Thanks,
Adithya
