associatedtype FormatInputDiscussion
Swift type inference uses this value to determine which static accessors are available at a given call point. For example, when you format an Int32, you can use the static number property that provides a IntegerFormatStyle<Int32>, as seen in the following example. This works because the style’s input type IntegerFormatStyle.FormatInput is a BinaryInteger generically constrained to the Int32 type.
let perihelionDistanceToSunInKm: Int32 = 147098291
perihelionDistanceToSunInKm.formatted(.number
.notation(.scientific)) // "1.470983E8"
