  3. def ## (): Int

    Equivalent to x.hashCode except for boxed numeric types.

    Equivalent to x.hashCode except for boxed numeric types. For numerics, it returns a hash value which is consistent with value equality: if two value type instances compare as true, then ## will produce the same hash value for each of them.

    returns

    a hash value consistent with ==

  18. def asInstanceOf [T0] : T0

    Cast the receiver object to be of type T0.

    Cast the receiver object to be of type T0.

    Note that the success of a cast at runtime is modulo Scala's erasure semantics. Therefore the expression 1.asInstanceOf[String] will throw a ClassCastException at runtime, while the expression List(1).asInstanceOf[List[String]] will not. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the requested type.

    returns

    the receiver object.

  20. def byteValue (): Byte

    Converts this BigDecimal to a Byte.

    Converts this BigDecimal to a Byte. If the BigDecimal is too big to fit in a Byte, only the low-order 8 bits are returned. Note that this conversion can lose information about the overall magnitude of the BigDecimal value as well as return a result with the opposite sign.

  21. def charValue : Char

    Converts this BigDecimal to a Char.

    Converts this BigDecimal to a Char. If the BigDecimal is too big to fit in a char, only the low-order 16 bits are returned. Note that this conversion can lose information about the overall magnitude of the BigDecimal value and that it always returns a positive result.

  22. def clone (): AnyRef

    Create a copy of the receiver object.

  24. def doubleValue (): Double

    Converts this BigDecimal to a Double. if this BigDecimal has too great a magnitude to represent as a double, it will be converted to Double.NEGATIVE_INFINITY or Double.POSITIVE_INFINITY as appropriate.

  25. def eq (arg0: AnyRef): Boolean

    Tests whether the argument (arg0) is a reference to the receiver object (this).

    Tests whether the argument (arg0) is a reference to the receiver object (this).

    The eq method implements an equivalence relation on non-null instances of AnyRef, and has three additional properties:

    • It is consistent: for any non-null instances x and y of type AnyRef, multiple invocations of x.eq(y) consistently returns true or consistently returns false.
    • For any non-null instance x of type AnyRef, x.eq(null) and null.eq(x) returns false.
    • null.eq(null) returns true.

    When overriding the equals or hashCode methods, it is important to ensure that their behavior is consistent with reference equality. Therefore, if two objects are references to each other (o1 eq o2), they should be equal to each other (o1 == o2) and they should hash to the same value (o1.hashCode == o2.hashCode).

    returns

    true if the argument is a reference to the receiver object; false otherwise.

  31. def hashCode (): Int

    Returns the hash code for this BigDecimal.

    Returns the hash code for this BigDecimal. Note that this does not use the underlying java object's hashCode because we compare BigDecimals with compareTo which deems 2 == 2.00, whereas in java these are unequal with unequal hashCodes.

  33. def isInstanceOf [T0] : Boolean

    Test whether the dynamic type of the receiver object is T0.

    Test whether the dynamic type of the receiver object is T0.

    Note that the result of the test is modulo Scala's erasure semantics. Therefore the expression 1.isInstanceOf[String] will return false, while the expression List(1).isInstanceOf[List[String]] will return true. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the specified type.

    returns

    true if the receiver object is an instance of erasure of type T0; false otherwise.

  76. def unifiedPrimitiveEquals (x: Any): Boolean

    Should only be called after all known non-primitive types have been excluded.

    Should only be called after all known non-primitive types have been excluded. This method won't dispatch anywhere else after checking against the primitives to avoid infinite recursion between equals and this on unknown "Number" variants.

    Additionally, this should only be called if the numeric type is happy to be converted to Long, Float, and Double. If for instance a BigInt much larger than the Long range is sent here, it will claim equality with whatever Long is left in its lower 64 bits. Or a BigDecimal with more precision than Double can hold: same thing. There's no way given the interface available here to prevent this error.

    Creates a partially constructed NumericRange[BigDecimal] in range [start;end), where start is the target BigDecimal. The step must be supplied via the "by" method of the returned object in order to receive the fully constructed range. For example:

    val partial = BigDecimal(1.0) to 2.0       // not usable yet
    val range = partial by 0.01                // now a NumericRange
    val range2 = BigDecimal(0) to 1.0 by 0.01  // all at once of course is fine too

    returns
