Framework
- Swift Standard Library
Declaration
init(_ other: Float)
Parameters
otherThe value to use for the new instance.
Discussion
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: Float = 21.25
let y = Double(x)
// y == 21.25
let z = Double(Float.nan)
// z.isNaN == true
