  2. final def ##(): Int

    Equivalent to x.hashCode except for boxed numeric types and null.

    Equivalent to x.hashCode except for boxed numeric types and null.

For null returns a hashcode where null.hashCode throws a NullPointerException.

    returns

    a hash value consistent with ==

    The expression x == that is equivalent to if (x eq null) that eq null else x.equals(that).

  21. final 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.

    the receiver object.

    Definition Classes
    Any
    Exceptions thrown

    ClassCastException if the receiver object is not an instance of the erasure of type T0.

  22. def binary(d: Double): BigDecimal

    Constructs a BigDecimal by expanding the binary fraction contained by Double value d into a decimal representation, rounding if necessary.

    Constructs a BigDecimal by expanding the binary fraction contained by Double value d into a decimal representation, rounding if necessary. When a Float is converted to a Double, the binary fraction is preserved, so this method also works for converted Floats.

  28. def decimal(f: Float): BigDecimal

    Constructs a BigDecimal using the decimal text representation of Float value f.

    Constructs a BigDecimal using the decimal text representation of Float value f. Note that BigDecimal.decimal(0.1f) != 0.1f since equality agrees with the Double representation, and 0.1 != 0.1f.

  29. def decimal(f: Float, mc: MathContext): BigDecimal

    Constructs a BigDecimal using the decimal text representation of Float value f, rounding if necessary.

    Constructs a BigDecimal using the decimal text representation of Float value f, rounding if necessary. Note that BigDecimal.decimal(0.1f) != 0.1f since equality agrees with the Double representation, and 0.1 != 0.1f.

  33. implicit def double2bigDecimal(d: Double): BigDecimal

  34. final def eq(arg0: AnyRef): Boolean

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

    Tests whether the argument (that) 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.

    AnyRef
  35. def equals(arg0: Any): Boolean

    The equality method for reference types.

    The equality method for reference types. Default implementation delegates to eq.

  39. def exact(bi: BigInt): BigDecimal

  40. def exact(d: Double): BigDecimal

    Constructs a BigDecimal by fully expanding the binary fraction contained by Double value d, adjusting the precision as necessary.

    Constructs a BigDecimal from a java.math.BigDecimal. The precision is the default for BigDecimal or enough to represent the java.math.BigDecimal exactly, whichever is greater.

    Called by the garbage collector on the receiver object when there are no more references to the object.

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

    Note that the result of the test is modulo Scala's erasure semantics.
