The radix, or base of exponentiation, for a floating-point type.
Declaration
static var radix: Int { get }Discussion
The magnitude of a floating-point value x of type F can be calculated by using the following formula, where ** is exponentiation:
x.significand * (F.radix ** x.exponent)A conforming type may use any integer radix, but values other than 2 (for binary floating-point types) or 10 (for decimal floating-point types) are extraordinarily rare in practice.
