The rule Compare of float numbers by equality operator warns for unintended comparison of values to a float variable value. However, we have many false positives since we need to compare them to constant values.
I suggest an attribute which can be set on the constant to ignore this rule.
public class Derp
public const float SpecialNullValue = 123.456;
Off course, we can use a resharper comment rule to disable this. However, this gets tedious and many false-positives demotivate devvers.
