You could store it in a file:

Code:
# Initial value used to compare.
val=$(cat /path/to/file.txt)

/path/to/file.txt
should contain only one line with the number and must exist in the first run in this case.
Finally:

Code:
echo "-----------"
echo "###########"
echo "-----------"
echo "val=$val"
echo $val > /path/to/file

So that you update the file with the new value.
