Example 1 with FuncSignLongToDouble

use of org.apache.hadoop.hive.ql.exec.vector.expressions.gen.FuncSignLongToDouble in project hive by apache.

the class TestVectorMathFunctions method testVectorSign.

@Test

    VectorExpression expr = new FuncSignDoubleToDouble(0, 1);
    expr.evaluate(b);
    Assert.assertEquals(-1.0d, resultV.vector[0]);
    Assert.assertEquals(1.0d, resultV.vector[4]);
    // test long->double version
    b = getVectorizedRowBatchLongInDoubleOut();
