Example 1 with FuncSqrtDoubleToDouble

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

the class TestVectorMathFunctions method testVectorSqrt.

@Test
public void testVectorSqrt() throws HiveException {
    VectorizedRowBatch b = getVectorizedRowBatchDoubleInDoubleOut();
    DoubleColumnVector resultV = (DoubleColumnVector) b.cols[1];
    b.cols[0].noNulls = true;
    VectorExpression expr = new FuncSqrtDoubleToDouble(0, 1);
    expr.evaluate(b);
    Assert.assertEquals(Math.sqrt(0.5d), resultV.vector[4], Double.MIN_VALUE);
