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.
associatedtype RawExponent : UnsignedIntegerA type that represents the encoded exponent of a value.
associatedtype RawSignificand : UnsignedIntegerA type that represents the encoded significand of a value.
init<Source>(Source)Creates a new instance from the given value, rounded to the closest possible representation.
init(Float)Creates a new instance from the given value, rounded to the closest possible representation.
init(Double)Creates a new instance from the given value, rounded to the closest possible representation.
init(Float80)Creates a new instance from the given value, rounded to the closest possible representation.
init?<Source>(exactly: Source)Creates a new instance from the given value, if it can be represented exactly.
init(sign: FloatingPointSign, exponentBitPattern: Self.RawExponent, significandBitPattern: Self.RawSignificand)Creates a new instance from the specified sign and bit patterns.
static var exponentBitCount: IntThe number of bits used to represent the type’s exponent.
static var significandBitCount: IntThe available number of fractional significand bits.
var binade: SelfThe floating-point value with the same sign and exponent as this value, but with a significand of 1.0.
var exponentBitPattern: Self.RawExponentThe raw encoding of the value’s exponent field.
var significandBitPattern: Self.RawSignificandThe raw encoding of the value’s significand field.
var significandWidth: IntThe number of bits required to represent the value’s significand.
static func random(in: ClosedRange<Self>) -> SelfReturns a random value within the specified range.
static func random(in: Range<Self>) -> SelfReturns a random value within the specified range.
static func random<T>(in: Range<Self>, using: inout T) -> SelfReturns a random value within the specified range, using the given generator as a source for randomness.
static func random<T>(in: ClosedRange<Self>, using: inout T) -> SelfReturns a random value within the specified range, using the given generator as a source for randomness.
