> TestGenericUDFPower.testDoulePowerDecimal() uses junit's Assert.assertEquals(double, double) to test double equality on result of power udf function.
> Due to floating-number convention, this does not always work.  This API is deprecated in favor of Assert.assertEquals(message, double, double, delta).
