To avoid confusion, and to allow for decimal floating-point types:
[stdlib/public/core/FloatingPointTypes.swift.gyb]
public struct Binary32: BinaryFloatingPoint
public struct Binary64: BinaryFloatingPoint
[stdlib/public/core/CTypes.swift]
public typealias CFloat = Binary32
public typealias CDouble = Binary64
You could also have:
public struct Binary /// The default, cf. Int
public typealias BinaryMax /// The largest, cf. IntMax
