Реализация типа-обёртки

Помогите исправить код. Я пишу тип-обёртку в проекте для нейронных сетей и я хочу чтобы изменяя в этой структуре тип с double на float, ufloat, double, udouble, ulong или другой числовой, все функции приведения типов, конструкторы, неявные преобразования работали корректно. Пожалуйста, посмотрите и исправьте в коде некорректные реализации:

    /// </summary>
    public struct NType : IComparable, IComparable<NType>, IConvertible, IEquatable<NType>, IFormattable
    {
        /// <summary>
        /// Значение, выражающее тип параметров нейрона
        /// Сейчас double, вы можете сменить тип, изменяя тип value, MinValue, MaxValue, Epsilon 
        /// </summary>
        readonly double value;
        public const double MinValue = double.MinValue;
        public const double MaxValue = double.MaxValue;
