Creates a new instance initialized to the given value.
init(_ other: Float) The 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: Float = 21.25
let y = Float(x)
// y == 21.25
let z = Float(Float.nan)
// z.isNaN == trueimport Swift@frozen struct FloatA single-precision, floating-point value type.
init() init(_ other: Double) 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: UInt32) 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.
init?(exactly other: Float16) Creates a new instance initialized to the given value, if it can be represented without rounding.
init?<Source>(exactly value: Source) where Source : BinaryInteger init(floatLiteral value: Float) init(from decoder: any Decoder) throws init(integerLiteral value: Int64) init(nan payload: Float.RawSignificand, signaling: Bool) Creates a NaN (“not a number”) value with the specified payload.
