Enumeration Cases
case negativeInfinity A value equal to -infinity.
case negativeNormal A negative value that uses the full precision of the floating-point type.
case negativeSubnormal A negative, nonzero number that does not use the full precision of the floating-point type.
case negativeZero A value equal to zero with a negative sign.
case positiveInfinity A value equal to +infinity.
case positiveNormal A positive value that uses the full precision of the floating-point type.
case positiveSubnormal A positive, nonzero number that does not use the full precision of the floating-point type.
case positiveZero A value equal to zero with a positive sign.
case quietNaN A silent NaN (“not a number”) value.
case signalingNaN A signaling NaN (“not a number”).
Instance Properties
var hashValue : IntThe hash value.
Instance Methods
func hash(into: inout Hasher)Hashes the essential components of this value by feeding them into the given hasher.
Operator Functions
static func != (FloatingPointClassification, FloatingPointClassification) -> Bool Returns a Boolean value indicating whether two values are not equal.
static func == (FloatingPointClassification, FloatingPointClassification) -> Bool Returns a Boolean value indicating whether two values are equal.
