Example 1 with FuncCosDoubleToDouble

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

the class TestVectorMathFunctions method testVectorCos.

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