We have a view that performs some trig calculations. It works when testing
in MySQL, but fails when using sqlite.
I have overridden the "RADIANS" function implementation from django in our
conftest.py file. Details not that important, but essentially is this:
```
connection.create_function("RADIANS", 1, lambda x: math.radians(float(x))
if x is not None else None)
```
The issue is, there is a lat/lon field in our database, which is stored as
a CharField (we can debate that decision later...), so when it gets passed
into the `_sqlite_radians` function the test fails as it is invalid input.
I think that these functions should be able to take in string values.
I have started a PR but thought before I submit it I should see if it is a
'genuine' bug or a decision not to support this field.
