init?(exactly other: Float16) Parameters
- other
The value to use for the new instance.
If other can’t be represented as an instance of Float without rounding, the result of this initializer is nil. In particular, passing NaN as other always results in nil.
let x: Float16 = 21.25
let y = Float(exactly: x)
// y == Optional.some(21.25)
let z = Float(exactly: Float16.nan)
// z == nil
