BinaryFloatingPoint
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.
Supertypes
protocol AdditiveArithmeticA type with values that support addition and subtraction.
protocol ComparableA type that can be compared using the relational operators
<,<=,>=, and>.protocol EquatableA type that can be compared for value equality.
protocol ExpressibleByFloatLiteralA type that can be initialized with a floating-point literal.
protocol ExpressibleByIntegerLiteralA type that can be initialized with an integer literal.
protocol FloatingPointA floating-point numeric type.
protocol HashableA type that can be hashed into a
Hasherto produce an integer hash value.protocol NumericA type with values that support multiplication.
protocol SignedNumericA numeric type with a negation operation.
protocol StrideableA type representing continuous, one-dimensional values that can be offset and measured.
Requirements

init(Double) 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<Source>(Source) 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.
