Declaration
var isSubnormal: Bool { get }Discussion
A subnormal value is a nonzero number that has a lesser magnitude than the smallest normal number. Subnormal values do not use the full precision available to values of a type.
Zero is neither a normal nor a subnormal number. Subnormal numbers are often called denormal or denormalized—these are different names for the same concept.
