At current, the DoubleExtensions class has a defined constant const double Epsilon = 1E-07.
I propose removing it to use the build-in double.Epsilon, then adding overloads to allow for custom variance, which seems to be the more modern approach in many other libraries.

This old post on StackOverflow describes that:

The System.Double type can represent values accurate to up to 15 digits. So a simple first order estimate if a double value x is equal to some constant is to use an epsilon of constant * 1E-15

Another post on the same thread suggests their own implementation, should you wish to keep a default variance:

/// <summary>
/// smallest such that 1.0+EpsilonD != 1.0
/// </summary>
public const double EpsilonD = 2.2204460492503131e-016;
