final class BigDecimal extends ScalaNumber with ScalaNumericConversions with Serializable

`BigDecimal` represents decimal floating-point numbers of arbitrary precision. By default, the precision approximately matches that of IEEE 128-bit floating point numbers (34 decimal digits, `HALF_EVEN` rounding mode). Within the range of IEEE binary128 numbers, `BigDecimal` will agree with `BigInt` for both equality and hash codes (and will agree with primitive types as well). Beyond that range--numbers with more than 4934 digits when written out in full--the `hashCode` of `BigInt` and `BigDecimal` is allowed to diverge due to difficulty in efficiently computing both the decimal representation in `BigDecimal` and the binary representation in `BigInt`.

When creating a `BigDecimal` from a `Double` or `Float`, care must be taken as the binary fraction representation of `Double` and `Float` does not easily convert into a decimal representation. Three explicit schemes are available for conversion. `BigDecimal.decimal` will convert the floating-point number to a decimal text representation, and build a `BigDecimal` based on that. `BigDecimal.binary` will expand the binary fraction to the requested or default precision. `BigDecimal.exact` will expand the binary fraction to the full number of digits, thus producing the exact decimal value corresponding to the binary fraction of that floating-point number. `BigDecimal` equality matches the decimal expansion of `Double`: `BigDecimal.decimal(0.1) == 0.1`. Note that since `0.1f != 0.1`, the same is not true for `Float`. Instead, `0.1f == BigDecimal.decimal((0.1f).toDouble)`.

To test whether a `BigDecimal` number can be converted to a `Double` or `Float` and then back without loss of information by using one of these methods, test with `isDecimalDouble`, `isBinaryDouble`, or `isExactDouble` or the corresponding `Float` versions. Note that `BigInt`'s `isValidDouble` will agree with `isExactDouble`, not the `isDecimalDouble` used by default.

`BigDecimal` uses the decimal representation of binary floating-point numbers to determine equality and hash codes. This yields different answers than conversion between `Long` and `Double` values, where the exact form is used. As always, since floating-point is a lossy representation, it is advisable to take care when assuming identity will be maintained across multiple conversions.

`BigDecimal` maintains a `MathContext` that determines the rounding that is applied to certain calculations. In most cases, the value of the `BigDecimal` is also rounded to the precision specified by the `MathContext`. To create a `BigDecimal` with a different precision than its `MathContext`, use `new BigDecimal(new java.math.BigDecimal(...), mc)`. Rounding will be applied on those mathematical operations that can dramatically change the number of digits in a full representation, namely multiplication, division, and powers. The left-hand argument's `MathContext` always determines the degree of rounding, if any, and is the one propagated through arithmetic operations that do not apply rounding themselves.

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.

17. 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.

28. final 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.

35. def hashCode(): Int

Returns the hash code for this BigDecimal.

Returns the hash code for this BigDecimal. Note that this does not merely use the underlying java object's `hashCode` because we compare `BigDecimal`s with `compareTo` which deems 2 == 2.00, whereas in java these are unequal with unequal `hashCode`s. These hash codes agree with `BigInt` for whole numbers up ~4934 digits (the range of IEEE 128 bit floating point). Beyond this, hash codes will disagree; this prevents the explicit representation of the `BigInt` form for `BigDecimal` values with large exponents.
