Examples with FloorDecimalExpression org.apache.phoenix.expression.function.FloorDecimalExpression used on opensource projects

Example 1 with FloorDecimalExpression

use of org.apache.phoenix.expression.function.FloorDecimalExpression in project phoenix by apache.

the class RoundFloorCeilExpressionsTest method testFloorDecimalExpression.

@Test
public void testFloorDecimalExpression() throws Exception {
    LiteralExpression decimalLiteral = LiteralExpression.newConstant(1.23898, PDecimal.INSTANCE);
    Expression floorDecimalExpression = FloorDecimalExpression.create(decimalLiteral, 3);
    ImmutableBytesWritable ptr = new ImmutableBytesWritable();
    floorDecimalExpression.evaluate(null, ptr);
    Object result = floorDecimalExpression.getDataType().toObject(ptr);
    assertTrue(result instanceof BigDecimal);
    BigDecimal resultDecimal = (BigDecimal) result;
    assertEquals(BigDecimal.valueOf(1.238), resultDecimal);
}

Example 2 with FloorDecimalExpression

use of org.apache.phoenix.expression.function.FloorDecimalExpression in project phoenix by apache.
