> {{RexInterpreter}} throws {{ClassCastException}} when evaluating {{SEARCH}}
> calls with NUMERIC arguments that don't have the same Class in their runtime
> representation. The most vivid example is when we compare approximate
> numerics with exact numerics.
> +Example+
> {code:sql}
> SELECT 10035e-2 IN (100, 200) AS foo;
> {code}
> The approximate numerics are internally represented using Double while exact
> numerics are represented using BigDecimal. The easiest way to reproduce the
> problem is through the simplifier which internally calls the interpreter.
> The following test can be added in {{{}RexProgramTest{}}}:
> {code:java}
> @Test void testSimplifySearch() {
> RexNode d100_35 = rexBuilder.makeApproxLiteral(100.35,
> typeFactory.createSqlType(SqlTypeName.DOUBLE));
> RexNode d100 = rexBuilder.makeExactLiteral(BigDecimal.valueOf(100),
> typeFactory.createSqlType(SqlTypeName.INTEGER));
> RexNode d200 = rexBuilder.makeExactLiteral(BigDecimal.valueOf(200),
> typeFactory.createSqlType(SqlTypeName.INTEGER));
> checkSimplify(rexBuilder.makeIn(d100_35, Arrays.asList(d100, d200)),"");
> }
> {code}
> {noformat}
> class java.math.BigDecimal cannot be cast to class java.lang.Double
> (java.math.BigDecimal and java.lang.Double are in module java.base of loader
> 'bootstrap')
