init(signOf:magnitudeOf:)
Creates a new floating-point value using the sign of one value and the magnitude of another.
Declaration
init(signOf sign: Float, magnitudeOf mag: Float)Discussion
The following example uses this initializer to create a new Double instance with the sign of a and the magnitude of b:
let a = -21.5
let b = 305.15
let c = Double(signOf: a, magnitudeOf: b)
print(c)
// Prints "-305.15"This initializer implements the IEEE 754 copysign operation.
