A radix-2 (binary) floating-point type.
protocol BinaryFloatingPoint : ExpressibleByFloatLiteral, FloatingPointThe BinaryFloatingPoint protocol extends the FloatingPoint protocol with operations specific to floating-point binary types, as defined by the IEEE 754 specification. BinaryFloatingPoint is implemented in the standard library by Float, Double, and Float80 where available.
