Replying to [comment:2 Mariusz Felisiak]:
> Thanks for this ticket, however `radians` should not accept strings. You
can cast values before passing them to this function.
Hi Mariusz, the sqlite docs specify that these functions should accept
strings (see https://www.sqlite.org/lang_mathfunc.html)
"The arguments to math functions can be integers, floating-point numbers,
or strings or blobs that look like integers or real numbers. If any
argument is NULL or is a string or blob that is not readily converted into
a number, then the function will return NULL."
Also - in this instance I am unable to cast the values because they are
calculated wholly within the view (which I can't change)
