true if !(this == that), false otherwise.
Equivalent to x.hashCode except for boxed numeric types and null.
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.

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

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.

ClassCastException if the receiver object is not an instance of the erasure of type T0.
Constructs a BigDecimal by expanding the binary fraction
contained by Double value d into a decimal representation.
Constructs a BigDecimal by expanding the binary fraction
contained by Double value d into a decimal representation.
Note: this also works correctly on converted Floats.
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.

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.

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:
x and y of type AnyRef, multiple invocations of
x.eq(y) consistently returns true or consistently returns false.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).
true if the argument is a reference to the receiver object; false otherwise.

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

Therefore the expression 1.isInstanceOf[String] will return false, while the

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.

(Since version 2.11) This method appears to round a java.math.BigDecimal but actually doesn't. Use new BigDecimal(bd, mc) instead for no rounding, or BigDecimal.decimal(bd, mc) for rounding.
(Since version 2.11) The default conversion from Float may not do what you want. Use BigDecimal.decimal for a String representation, or explicitly convert the Float with .toDouble.
