true
if !(this == that), false otherwise.
Equivalent to x.hashCode
except for boxed numeric types and null
. 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. For null
returns a hashcode where null.hashCode
throws a NullPointerException
.
a hash value consistent with ==
The expression x == that
is equivalent to if (x eq null) that eq null else x.equals(that)
.
true
if the receiver object is equivalent to the argument; false
otherwise.

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.

Constructs a BigDecimal
by expanding the binary fraction contained by Double
value d
into a decimal representation. Note: this also works correctly on converted Float
s.
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 Float
s.
Create a copy of the receiver object.

method is platform dependent.

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

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:
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
).

if the argument is a reference to the receiver object; false

if the receiver object is equivalent to the argument; false

Constructs a BigDecimal
that exactly represents a Long
. Note that all creation methods for BigDecimal
that do not take a MathContext
represent a Long
; this is equivalent to apply
, valueOf
, etc..
Constructs a BigDecimal
by fully expanding the binary fraction contained by Double
value d
, adjusting the precision as necessary. Note: this works correctly on converted Float
s also.
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.
The details of when and if the finalize
method is invoked, as well as the interaction between finalize
and non-local returns and exceptions, are all platform dependent.

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.
