    public static float NAN;

    Description

    Single precision constant for Not a Number.

    NAN is considered unordered, which means all comparisons involving it are false except for not equal (operator !=). As a consequence, NAN == NAN is false but NAN != NAN is true.

    Additionally, there are multiple bit representations for Not a Number, so if you must test if your value is NAN, use isnan().

    Is something described here not working as you expect it to? It might be a Known Issue. Please check with the Issue Tracker at issuetracker.unity3d.com.
