        @Override
        public BigDecimal provideRandom(Random random) {
            return BigDecimal.valueOf(10000.0D + random(1000, 2000));
        }
    }, BigDecimal.class);
    BigDecimal expectation = BigDecimal.ZERO;
    for (int i = 0; i < values.length; i++) {
        BigDecimal value = values[i];
        expectation = i == 0 ? value : expectation.max(value);
    }
    Aggregation<String, BigDecimal, BigDecimal> aggregation = Aggregations.bigDecimalMax();
    BigDecimal result = testMax(values, aggregation);
    assertEquals(expectation, result);
}

}

Example 84 with BigDecimal

use of java.math.BigDecimal in project guava by hceylan.

the class BigIntegerMath method divide.

/**
   * Returns the result of dividing {@code p} by {@code q}, rounding using the specified
   * {@code RoundingMode}.
   *
   * @throws ArithmeticException if {@code q == 0}, or if {@code mode == UNNECESSARY} and {@code a}
   *         is not an integer multiple of {@code b}
   */
public static BigInteger divide(BigInteger p, BigInteger q, RoundingMode mode) {
    BigDecimal pDec = new BigDecimal(p);
    BigDecimal qDec = new BigDecimal(q);
    return pDec.divide(qDec, 0, mode).toBigIntegerExact();
}

Example 85 with BigDecimal

use of java.math.BigDecimal in project guava by google.

the class LongMathTest method computeMeanSafely.

/**
   * Computes the mean in a way that is obvious and resilient to
   * overflow by using BigInteger arithmetic.
   */
private static long computeMeanSafely(long x, long y) {
    BigInteger bigX = BigInteger.valueOf(x);
    BigInteger bigY = BigInteger.valueOf(y);
    BigDecimal bigMean = new BigDecimal(bigX.add(bigY)).divide(BigDecimal.valueOf(2), BigDecimal.ROUND_FLOOR);
    // parseInt blows up on overflow as opposed to intValue() which does not.
    return Long.parseLong(bigMean.toString());
