Description Nathan Abramson 2002-04-15 13:54:25 UTC 
A new clause has been added to the rules for relational operators (<,
>, <=, >=)

  if A==B, if operator is <=, le, >= or ge return true otherwise return false
++if A is null or B is null, return false
  if A or B is Float or Double coerce both A and B to Double apply operator

Add this rule to the implementation
Comment 1 Nathan Abramson 2002-04-15 14:24:30 UTC 
Fixed by changing the LessThanOperator, LessThanOrEqualsOperator,
GreaterThanOperator, GreaterThanOrEqualsOperator
