While looking at #28721, I realised that there is loss of precision on
large integer literals:
{{{
#!python
>>> from django.template import Template, Context
>>> Template('{{ 999999999999999999999999999 }}').render(Context())
u'1000000000000000013287555072'
}}}
This happens because the code tries to first convert literal values to a
**float** and then from the **float** to an **int**, which is a lossy
operation.
