A 128-bit IEEE 754-2008 decimal floating point number.

This type is similar to Swift’s built-in Decimal type, but allocates bits differently, resulting in a different representable range. (NS)Decimal stores a significand of up to 38 digits long and an exponent from -128 to 127, while this type stores up to 34 digits of significand and an exponent from -6143 to 6144.

  • Creates a new zero-initialized Decimal128.

    Declaration

    Swift

    public override required init()
    Show on GitHub

  • Converts the given value to a Decimal128.

    The following types can be converted to Decimal128:

    • Int (of any size)
    • Float
    • Double
    • String
    • NSNumber
    • Decimal

    Passing a value with a type not in this list is a fatal error. Passing a string which cannot be parsed as a valid Decimal128 is a fatal error.

    Declaration

    Swift

    public override required init(value: Any)

    Parameters

    value

    The value to convert to a Decimal128.

  • Converts the given number to a Decimal128.

    This initializer cannot fail and is never lossy.

    Declaration

    Swift

    public override required init(number: NSNumber)

    Parameters

    number

    The number to convert to a Decimal128.

  • Parse the given string as a Decimal128.

    This initializer never throws and is marked as throws only because removing it is a breaking change. Strings which cannot be parsed as a Decimal128 return a value where isNaN is true.

    Declaration

    Swift

    public override required init(string: String) throws

    Parameters

    string

    The string to parse.

  • Creates a new Decimal128 by decoding from the given decoder.

    This initializer throws an error if the decoder is invalid or does not decode to a value which can be converted to Decimal128.

    Declaration

    Swift

    public required init(from decoder: Decoder) throws

    Parameters

    decoder

    The decoder to read data from.

  • min

    The mininum value for Decimal128

    Declaration

    Swift

    public static var min: Decimal128 { get }
    Show on GitHub
  • max

    The maximum value for Decimal128

    Declaration

    Swift

    public static var max: Decimal128 { get }

  • Encodes this Decimal128 to the given encoder.

    This function throws an error if the given encoder is unable to encode a string.

    Declaration

    Swift

    public func encode(to encoder: Encoder) throws

    Parameters

    encoder

    The encoder to write data to.

  • Creates a new instance from the given integer, if it can be represented exactly.

    If the value passed as source is not representable exactly, the result is nil. In the following example, the constant x is successfully created from a value of 100, while the attempt to initialize the constant y from 1_000 fails because the Int8 type can represent 127 at maximum:

    Declaration

    Swift

    public convenience init?<T>(exactly source: T) where T : BinaryInteger

    Parameters

    source

    A value to convert to this type of integer.

  • Returns a Decimal128 that is offset the specified distance from this value.

    Use the advanced(by:) method in generic code to offset a value by a specified distance. If you’re working directly with numeric values, use the addition operator (+) instead of this method.

    Declaration

    Swift

    n
