Initializerswift 6.0.3Swift

init(_:)

Creates a new instance that approximates the given value.

init(_ other: Double)

Parameters

other

The value to use for the new instance.

The value of other is rounded to a representable value, if necessary. 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 = Float(x)
// y == 21.25

let z = Float(Double.nan)
// z.isNaN == true
