Example 1 with Decimal128

use of de.undercouch.bson4jackson.types.Decimal128 in project bson4jackson by michel-kraemer.

the class BsonGeneratorTest method writeBigDecimalsAsDecimal128s.

/**
 * Test if {@link BigDecimal} objects can be serialized as {@link Decimal128}s
 * @throws Exception if something goes wrong
 */
@Test
public void writeBigDecimalsAsDecimal128s() throws Exception {
    Map<String, Object> data = new LinkedHashMap<String, Object>();
    data.put("big", new BigDecimal("0.3"));
    BSONObject obj = generateAndParse(data);
    Double result = (Double) obj.get("big");
    // BigDecimal("0.3") does not equal 0.3!
    assertEquals(0.3, result, 0.000001);
    assertFalse(Double.valueOf(0.3).equals(result));
    data = new LinkedHashMap<String, Object>();
    data.put("big", new BigDecimal("0.3"));
    obj = generateAndParse(data, Feature.WRITE_BIGDECIMALS_AS_DECIMAL128);
    org.bson.types.Decimal128 strResult = (org.bson.types.Decimal128) obj.get("big");
    assertEquals(new BigDecimal("0.3"), strResult.bigDecimalValue());
}
