Description

there are only 3 power methods:
double power(double b0, double b1)
double power(long b0, long b1)
double power(long b0, BigDecimal b1)
in org.apache.calcite.runtime.SqlFunctions

but methods are unsuitable with double power(double b0, BigDecimal b1)

@Test public void testPowerFuncWithDec() {
        tester.setFor(SqlStdOperatorTable.POWER);
        tester.checkScalarApprox("power(cast(10 as double), cast(2 as decimal))", "DOUBLE NOT NULL", 100d, 0);
    }

got exception:

java.lang.RuntimeException: java.sql.SQLException: Error while executing SQL "values (power(cast(10 as double), cast(2 as decimal)))": while resolving method 'power[double, class java.math.BigDecimal]' in class class org.apache.calcite.runtime.SqlFunctions
