[comphead]

Which issue does this PR close?

Part of #4150 .

Wire rint Apache Spark built in function

Rationale for this change

What changes are included in this PR?

How are these changes tested?

[martin-g]

Some other unary math tests do literal arguments verification too

Suggested change

	SELECT rint(v + 0.5) FROM test_rint
	SELECT rint(v + 0.5) FROM test_rint
	-- literal arguments
	query
	SELECT rint(0.5), rint(1.5), rint(-0.5), rint(2.5), rint(NULL), rint(cast('NaN' as double))

Thanks @martin-g in Comet we dont test EmptyRelation queries, Comet expects a source

I was confused by some examples in the other tests:

• datafusion-comet/spark/src/test/resources/sql-tests/expressions/math/expm1.sql

  Line 29 in b7bb47d

  SELECT expm1(0.0), expm1(1.0), expm1(NULL)

• datafusion-comet/spark/src/test/resources/sql-tests/expressions/math/ceil.sql

  Line 31 in b7bb47d

  SELECT ceil(1.1), ceil(-1.1), ceil(0.0), ceil(NULL), ceil(cast(1.10 as DECIMAL(5, 2))), ceil(cast(-1.10 as DECIMAL(5, 2)))

• datafusion-comet/spark/src/test/resources/sql-tests/expressions/math/floor.sql

  Line 31 in b7bb47d

  SELECT floor(1.9), floor(-1.1), floor(0.0), floor(NULL), floor(cast(1.90 as DECIMAL(5, 2))), floor(cast(-1.10 as DECIMAL(5, 2)))

• datafusion-comet/spark/src/test/resources/sql-tests/expressions/math/signum.sql

  Line 29 in b7bb47d

  SELECT signum(-5.0), signum(5.0), signum(0.0), signum(NULL)

The idea is to test the UDF with a ScalarValue, so adding FROM respective_table is a quick fix.

oh I see, makes sense, I'll add this in follow up PR, thanks!
