$POE runs a system which is extensively Linux, and part of the system
is a small script which monitors the free space various devices using
some third party software.
The software isn't the issue - doing the math to work out the
percentage free is.

I think you want to use bc to calculate the percentage.
the lines
free_var=${free%.*};
total_var=${total%.*};
are removing everything after the decimal point, which leaves 2/2 * 100
which is of course 100%
I presume it does this so that bash can then perform the arithmetic
evaluation
err, sorry, missed a closing quote
per=`echo ($free/$total) * 100 | bc -l`

Course they're not numbers if they look like '2.47T' or
