init() init(_ other: Double) Creates a new instance initialized to the given value.
init(_ other: Float) Creates a new instance that approximates the given value.
init?(_ text: Substring) init?<S>(_ text: S) where S : StringProtocol Creates a new instance from the given string.
init(_ v: Int) init(_ other: Float16) Creates a new instance that approximates the given value.
init<Source>(_ value: Source) where Source : BinaryInteger init(bitPattern: UInt64) Creates a new value with the given bit pattern.
init?(exactly other: Double) Creates a new instance initialized to the given value, if it can be represented without rounding.
init?(exactly other: Float) Creates a new instance initialized to the given value, if it can be represented without rounding.
