Implementation of an attribute for properties with System.Double Type to indicate the level of precision?

[Diego Frata]

That's interesting and definitely could be added for floating number types!

[Diego Frata]

Could probably call it PrecisionEquality

Version 2.2.0 now supports the attribute CustomEquality, which can be used to bridge any specific case not built into the library, including comparing doubles.

I will leave this issue open however, because I think this should be implemented at some point.

I was experimenting with an implementation using generics to target any floating point type using generic attributes and generic math with IFloatingPoint<T>. Though that would be restricted to .NET 7 and newer (with C# 11 compiler).

[GeneratedCode("Generator.Equals", "1.0.0.0")]
[Conditional("GENERATOR_EQUALS")]
[AttributeUsage(AttributeTargets.Property | AttributeTargets.Field)]
public class PrecisionEqualityAttribute<T> : Attribute
    where T : IFloatingPoint<T>
{
    public T Precision { get; }

    public PrecisionEqualityAttribute(T precision)
    {
        Precision = precision;
    }
}
