hi vgersh. i just copied whatever you gave me. this is the code

Code:
$SIEBEL_ROOT/bin/srvrmgr -g $SIEBEL_GATEWAY -e $SIEBEL_ENTERPRISE -s $SIEBEL_SERVER -u n9912499 -p n9912499 -c "list component 'eCustomerCMEObjMgr_enu'" -o "$temp_output"  
# set -x
num_tasks=`sqlplus -s batch_user/batch_user@$SIEBEL_DB_ORACLESID << EOF2 
set heading off
SET FEEDBACK OFF
SET PAGESIZE 0
SET LINESIZE 900
select cp_num_run_ / cp_max_task 
      from fusionhc_chk 
      where cc_alias = 'eCustomerCMEObjMgr_enu';
EOF2`
echo $num_tasks
set -x
if [ "$(echo "if (${num_tasks} > '.95') 1" | bc)" -eq 1 ]; then
   echo "not good"
fi
exit

i still get this error

Code:
.15
+ bc
+ echo if (                 .15 > '.95') 1
syntax error on line 1, teletype
+ [  -eq 1 ]
+ exit

then
echo $a is greater
else

fi

Regards,
sorry,
test with 'b=1.1'

the bottom line is you cannot compare floats 'as floats' with ksh88 - that's what Solaris has.

Strange
Thanks for pointing out that. But why is it so, Vgersh? Is this a limitation?
