init(_ other: Double)
otherThe value to use for the new instance.
The value of other is represented exactly by the new instance. A NaN passed as other results in another NaN, with a signaling NaN value converted to quiet NaN.
let x: Double = 21.25
let y = Double(x)
// y == 21.25
let z = Double(Double.nan)
// z.isNaN == true
init<Source>(Source)Creates a new instance from the given value, rounded to the closest possible representation.
init(Float)Creates a new instance that approximates the given value.
init(Float80)Creates a new instance that approximates the given value.
init(CGFloat)Creates a new instance initialized to the given value.
init(sign: FloatingPointSign, exponent: Int, significand: Double)Creates a new value from the given sign, exponent, and significand.
init(signOf : Double, magnitudeOf : Double)Creates a new floating-point value using the sign of one value and the magnitude of another.
init<Source>(Source)Creates a new value, rounded to the closest possible representation.
