      • intValue

        public int intValue()
        Converts this Decimal128 to a int. This conversion is analogous to the narrowing primitive conversion from double to int as defined in The Java™ Language Specification: any fractional part of this Decimal128 will be discarded, and if the resulting integral value is too big to fit in a int, only the low-order 32 bits are returned. Note that this conversion can lose information about the overall magnitude and precision of this Decimal128 value as well as return a result with the opposite sign. Note that #NEGATIVE_ZERO is converted to 0.
        Specified by:
        intValue in class Number
        Returns:
        this Decimal128 converted to a int.
        Since:
        3.10
      • longValue

        public long longValue()
        Converts this Decimal128 to a long. This conversion is analogous to the narrowing primitive conversion from double to long as defined in The Java™ Language Specification: any fractional part of this Decimal128 will be discarded, and if the resulting integral value is too big to fit in a long, only the low-order 64 bits are returned. Note that this conversion can lose information about the overall magnitude and precision of this Decimal128 value as well as return a result with the opposite sign. Note that #NEGATIVE_ZERO is converted to 0L.
        Specified by:
        longValue in class Number
        Returns:
        this Decimal128 converted to a long.
        Since:
        3.10
      • floatValue

        public float floatValue()
        Converts this Decimal128 to a float. This conversion is similar to the narrowing primitive conversion from double to float as defined in The Java™ Language Specification: if this Decimal128 has too great a magnitude to represent as a float, it will be converted to Float.NEGATIVE_INFINITY or Float.POSITIVE_INFINITY as appropriate. Note that even when the return value is finite, this conversion can lose information about the precision of the Decimal128 value. Note that #NEGATIVE_ZERO is converted to 0.0f.
        Specified by:
        floatValue in class Number
        Returns:
        this Decimal128 converted to a float.
        Since:
        3.10
      • doubleValue

        public double doubleValue()
        Converts this Decimal128 to a double. This conversion is similar to the narrowing primitive conversion from double to float as defined in The Java™ Language Specification: if this Decimal128 has too great a magnitude to represent as a double, it will be converted to Double.NEGATIVE_INFINITY or Double.POSITIVE_INFINITY as appropriate. Note that even when the return value is finite, this conversion can lose information about the precision of the Decimal128 value. Note that #NEGATIVE_ZERO is converted to 0.0d.
        Specified by:
        doubleValue in class Number
        Returns:
        this Decimal128 converted to a double.
        Since:
        3.10
      • equals

        public boolean equals​(Object o)
        Returns true if the encoded representation of this instance is the same as the encoded representation of o.

        One consequence is that, whereas Double.NaN != Double.NaN, new Decimal128("NaN").equals(new Decimal128("NaN") returns true.

        Another consequence is that, as with BigDecimal, new Decimal128("1.0").equals(new Decimal128("1.00") returns false, because the precision is not the same and therefore the representation is not the same.

        Overrides:
        equals in class Object
        Parameters:
        o - the object to compare for equality
        Returns:
        true if the instances are equal
      • hashCode

        public int hashCode()
        Overrides:
        hashCode in class Object
