Examples with LongDecimalWithOverflowState io.prestosql.operator.aggregation.state.LongDecimalWithOverflowState used on opensource projects

Example 1 with LongDecimalWithOverflowState

use of io.prestosql.operator.aggregation.state.LongDecimalWithOverflowState in project hetu-core by openlookeng.

the class TestDecimalSumAggregation method testCombineOverflow.

@Test
public void testCombineOverflow() {
    addToState(state, TWO.pow(125));
    addToState(state, TWO.pow(126));
    LongDecimalWithOverflowState otherState = new LongDecimalWithOverflowStateFactory().createSingleState();
    addToState(otherState, TWO.pow(125));
    addToState(otherState, TWO.pow(126));
    DecimalSumAggregation.combine(state, otherState);
    assertEquals(state.getOverflow(), 1);
    assertEquals(state.getLongDecimal(), unscaledDecimal(TWO.pow(126)));
}

Example 2 with LongDecimalWithOverflowState

use of io.prestosql.operator.aggregation.state.LongDecimalWithOverflowState in project hetu-core by openlookeng.

the class TestDecimalSumAggregation method testCombineUnderflow.

@Test
public void testCombineUnderflow() {
    addToState(state, TWO.pow(125).negate());
    addToState(state, TWO.pow(126).negate());
    LongDecimalWithOverflowState otherState = new LongDecimalWithOverflowStateFactory().createSingleState();
    addToState(otherState, TWO.pow(125).negate());
    addToState(otherState, TWO.pow(126).negate());
    DecimalSumAggregation.combine(state, otherState);
    assertEquals(state.getOverflow(), -1);
    assertEquals(state.getLongDecimal(), unscaledDecimal(TWO.pow(126).negate()));
