Exponentiation operator in Swift

Question

I don\'t see an exponentiation operator defined in the base arithmetic operators in the Swift language reference.

Is there really no predefined integer or float ex

Answer 1

I did it like so:

operator infix ** { associativity left precedence 200 }

func ** (base: Double, power: Double) -> Double {
    return exp(log(base) * power)
}
