Example 1 with FuncATanDoubleToDouble

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

the class TestVectorMathFunctions method testVectorATan.

@Test
public void testVectorATan() {
    VectorizedRowBatch b = getVectorizedRowBatchDoubleInDoubleOut();
    DoubleColumnVector resultV = (DoubleColumnVector) b.cols[1];
    b.cols[0].noNulls = true;
    VectorExpression expr = new FuncATanDoubleToDouble(0, 1);
    expr.evaluate(b);
    Assert.assertEquals(Math.atan(0.5d), resultV.vector[4]);
