✅ Creating a number generically?

Is it possible to do this? For example, here's this basic method that gets the digits of any object implementing INumber:

    public static IEnumerable<TNumber> GetDigits<TNumber>(TNumber number, TNumber ten) where TNumber : INumber<TNumber>
    {
        List<TNumber> digits = new();
        while (number > TNumber.Zero)
        {
            digits.Add(number % ten);
            number /= ten;
        }

        digits.Reverse();
        return digits;
    }

    public static IEnumerable<TNumber> GetDigits<TNumber>(TNumber number, TNumber ten) where TNumber : INumber<TNumber>
    {
        List<TNumber> digits = new();
        while (number > TNumber.Zero)
        {
            digits.Add(number % ten);
            number /= ten;
        }

        digits.Reverse();
        return digits;
    }

Instead of having to pass 10 into the method, would there be a way to create the 10 inside of the method to hide it from the user?

INumber<T> implements INumberBase<T> which has a couple Create... methods So TNumber.CreateChecked(10), TNumber.CreateSaturating(10), or TNumber.CreateTruncating(10) should work

Ah that works, thank you
