<PRE>
public static int <B>compareWithConversion</B>(java.lang.Object v1, java.lang.Object v2)</PRE>
<DL>
<DD>Compares two objects for equality, even if it has to convert one of them to the other type. If both objects are numeric they are converted to the widest type and compared. If one is non-numeric and one is numeric the non-numeric is converted to double and compared to the double numeric value. If both are non-numeric and Comparable and the types are compatible (i.e. v1 is of the same or superclass of v2's type) they are compared with Comparable.compareTo(). If both values are non-numeric and not Comparable or of incompatible classes this will throw and IllegalArgumentException.
