Either replace the suffix 'Ex' in type name MathEx with the suggested numeric alternate '2' or provide a more meaningful suffix that distinguishes it from the type it replaces (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1711)

Nullability of reference types in type of parameter 'y' of 'int HistogramIterationValueComparer.Compare(object x, object y)' doesn't match implicitly implemented member 'int IComparer.Compare(object? x, object? y)' (possibly because of nullability attributes).
