No, we don't and we should test them. I think we have to create separate
jira for testing math functions, because code changes from this PR doesn't
affect logic of any math function, and while testing math function there will
be other issues not connected with with functionality (like BigInteger
constructor doesn't accept NaN, Infinity and others)

> Add session options to allow drill working with non standard json strings
> number literals like: NaN, Infinity, -Infinity. By default these options will
> be switched off, the user will be able to toggle them during working session.
> *For documentation*
> 1. Added two session options {{store.json.reader.non_numeric_numbers}} and
> {{store.json.reader.non_numeric_numbers}} that allow to read/write NaN and
> Infinity as numbers. By default these options are set to false.
> 2. Extended signature of {{convert_toJSON}} and {{convert_fromJSON}}
> functions by adding second optional parameter that enables read/write NaN and
> Infinity.
> For example:
> {noformat}
> select convert_fromJSON('{"key": NaN}') from (values(1)); will result with
> JsonParseException, but
> select convert_fromJSON('{"key": NaN}', true) from (values(1)); will parse
> NaN as a number.
> {noformat}
