Dividing two numbers in unix

Hi,

I have written this code the division of two numbers and multiply it by hundred (to get the percent)
Code:
echo "script running for the 1st time"
cp value_directory_present.txt /home/mysql_cnbc/value_directory_past.txt
rm -f test6.txt value_directory_present.txt
else
y1=`awk '{print $1}' value_directory_past.txt`
z=`expr $y - $y1`
echo $z
if [ $z = 0 ];then
echo "rate is zero"
rm -f value_directory_present.txt test6.txt test7.txt
break
else
z1=`$z/$y1`
echo $z1
z2=`100 * $z1`


when i am executing it i am getting this error .
Code:
+ find . -type f -name value_directory_past.txt
+ var=./value_directory_past.txt
+ [ ./value_directory_past.txt == '' ]
+ awk '{print $1}' value_directory_past.txt
+ y1=23789264
+ expr 23789328 - 23789264
+ z=64
+ echo 64
64
+ [ 64 = 0 ]
+ 64/23789264

test4.sh: line 32: 64/23789264: not found

+ z1=''
+ echo

Please suggest.Smilie

ZIPARCHIVE.ADDFILE(3)							 1						     ZIPARCHIVE.ADDFILE(3)

ZipArchive::addFile - Adds a file to a ZIP archive from the given path

SYNOPSIS
bool ZipArchive::addFile NULL (string $filename, [string $localname], [int $start], [int $length]) DESCRIPTION
Adds a file to a ZIP archive from a given path. PARAMETERS
o $filename - The path to the file to add. o $localname - If supplied, this is the local name inside the ZIP archive that will override the $filename. o $start - This parameter is not used but is required to extend ZipArchive. o $length - This parameter is not used but is required to extend ZipArchive. RETURN VALUES
Returns TRUE on success or FALSE on failure. EXAMPLES
This example opens a ZIP file archive test.zip and add the file /path/to/index.txt. as newname.txt. Example #1 Open and add <?php $zip = new ZipArchive; if ($zip->open('test.zip') === TRUE) { $zip->addFile('/path/to/index.txt', 'newname.txt'); $zip->close(); echo 'ok'; } else { echo 'failed'; } ?> NOTES
Note When a file is set to be added to the archive, PHP will lock the file. The lock is only released once the ZipArchive object has been closed, either via ZipArchive::close or the ZipArchive object being destroyed. This may prevent you from being able to delete the file being added until after the lock has been released. PHP Documentation Group ZIPARCHIVE.ADDFILE(3)
