The problem

The following math operations can be performed on Decimal with FoundationEssentials:

import FoundationEssentials

let number: Decimal = 2.0
let added = number + number
let subtracted = number - number
let multiplied = number * number
let divided = number / number

However, raising aDecimal to a power requires Foundation:

import Foundation

let number: Decimal = 2.0
let raised = pow(number, 2)

The solution

• The power operation should be available in FoundationEssentials alongside the basic decimal arithmetic operations.
• An exponentiation operator could be offered here to be consistent with the existing inline operator support (Python uses **, for example).

Additional context

• My app is particularly sensitive to binary size, so it's unfortunate that I have to import Foundation on non-Darwin platforms just for this somewhat essential function.
• func pow(_ x: Decimal, _ y: Int) -> Decimal in Foundation appears to be a wrapper around NSDecimalPower().
• The NSDecimalX() functions are part of Foundation, not FoundationEssentials.
• NSDecimalAdd, NSDecimalSubtract, NSDecimalMultiply, and NSDecimalDivide are available in FoundationEssentials via operators, but an equivalent for NSDecimalPower() is not offered.
