I don't know what the experts will advise but you might have to write one yourself. https://docs.djangoproject.com/en/1.10/howto/custom-template -tags/
However, I believe the accepted wisdom is that computation in the template is more expensive than in the view. Hence I would likely do it there in ordinary Python and pass a straight result to the template.
That said, you might also consider https://pypi.python.org/pypi/django-mathfilters
<table class="table table-striped">
<thead>
<tr>
<th>Net Balance</th>
<th>Post Date</th>
<th> GL rate</th>
</thead>
</tr>
{%for a in results%}
<tr>
<td>{{a.0}}</td>
<td>{{a.1}}</td>
<td>{{a.1/a.0}}</td>
</tr>
{%endfor%}
</table>

`{{results|pprint}}` is pretty clear. You have a list of
tuple. Tuples have no named member so a.nat_balance return a
None value.
{{ a.0 }} in your django template is the equivalent of a[0] in
python.
If you want dict-like object, your problem is with SQLalchemy,
not django

Try `{{ results | pprint }}` in your template.
That will not solve your problems but that
will give you a lot more information about
what data have been passed to your template.
